How to Write a Biology Essay

In this article, we will guide you on how to write a perfect biology essay from scratch. You’ll find various tips to help you excel in writing your essay and creating a paper worth the highest grades. We also prepared a jellyfish essay example for you, so it can be easier to enhance all the specifics and structure of this kind of paper.

What is Biology Essay

A biology essay is a student-written work where you present arguments and ideas about a particular biological topic. The essay on biology can take different forms like argumentative, cause-and-effect, descriptive, detailed analysis, or ‘how-to’ instruction, depending on the professor’s guidelines and writer’s preferences. 

A descriptive paper can explain a biological subject, while an argumentative one provides evidence to support a point of view. It’s up to you to choose which type is more suitable for the topic you’re writing about. The most common type is a cause-and-effect essay explaining an event’s reasons and consequences. 

How to Craft a Perfect Essay About Biology

Writing is an art form that requires time and effort. But if you prefer someone else to write the paper for you, you can just text the experts, ‘ do my homework for me ,’ and consider it done. 

Here is the step by step instruction to organize the process for desired results. 

Choose Your Biology Essay Topic

To get a good grade:

• make your paper informative and enjoyable by choosing a topic you wish to explore. 
• Use a brainstorming technique to generate 30-50 options for biology essay topics and research to create a shortlist. 
• Keep a notebook to jot down your ideas.

Choose a Question for Research

When writing a biology essay, use a scientific approach by selecting a research question related to your topic. Always avoid overly complex or apparent questions. You can also text our profs ‘ write my research paper ,’ and it can be done in a blink.

Create an Outline

Always have a clear plan when writing biology essays while starting a paper. Use a 5-paragraph structure with an outline to keep your main idea and arguments organized. Use any format that works best for you and adjust as needed. Discard any ideas that don’t fit your research question.

Use a Strong Thesis Statement

The introduction should end with a strong thesis statement synthesizing the overall essay, conveying the research question and your point of view. The paper is ineffective without a clear thesis, as readers may not understand your position.

Use Citation and References

Include a list of references in your academic papers, such as biology essays, to avoid plagiarism and provide data sources. Use the appropriate citation style, like APA or CSE, and consult a guide for requirements.

How to Structure a Biology Essay

Ensure your essay has an attention-grabbing introduction, a detailed body, and a solid conclusion with distinct sections. Use around seven paragraphs for the main body, adjusting as needed for the required word count.

Biology Essay Introduction

In the introduction of your essay about biology, showcase your expertise by providing a brief background of the topic and stating the essay’s objective. For a research paper, explain why the study is relevant. Make sure the reader understands the essence of your subject.

The body section of your essay on biology should focus on supporting and defending your thesis statement. To achieve this, make a list of essential points to cover and address each one step by step. Starting a new paragraph for each point ensures neatness and a continuous flow. 

In conclusion, restate your thesis statement and summarize supporting points to solidify your arguments. Avoid introducing new concepts, and leave a lasting impression on your instructor.

Jellyfish Essay - Example of a Biology Essay About a Fascinating Creature of the Ocean

Jellyfish, also known as jellies, are incredible creatures of the ocean. They’re members of the phylum Cnidaria, including corals and sea anemones. You can find jellyfish in every ocean around the globe, from the surface to the depths of the sea. 

Do you know what shape the jellyfish body has?! It’s one of their most unique features. Their bell-shaped body comprises a soft, jelly-like substance called mesoglea, found between two cellular layers. The outer layer of cells, the epidermis, is thin and flexible, while the inner layer, the gastrodermis, contains the jellyfish’s digestive system. At the bottom of the bell is the mouth, surrounded by tentacles armed with stinging cells called nematocysts. 

The jellyfish tentacles consist of venom-filled sacs, which can be potentially dangerous and life-threatening. Considering the severity of its sting, researchers have gathered information on how to treat it effectively. Use thick clothing, tweezers, sticks, or gloves to alleviate the sting. It’s crucial to avoid touching the sting with bare skin since the venom can cause severe harm. Always dispose of the tool used for removing the sting to prevent re-stinging. 

Jellyfish are creatures that feed on small fish and other tiny marine organisms. They capture their prey using the tentacles and bring it to their mouth. Once the food is inside the jellyfish, it’s broken down by digestive enzymes and absorbed into the gastrovascular cavity. 

An exciting thing about jelly is its life cycle. They go through several stages of development, starting as a tiny, free-swimming larva and then growing into a polyp. The polyp stage is stationary, and the jellyfish attaches itself to a surface using a sticky pad. During this stage, the jellyfish reproduces asexually, creating clones of itself. These clones then break off from the polyp and develop into the familiar bell-shaped body of the adult jellyfish. 

Jellyfish play an essential role in the ocean’s ecosystem too. They’re a food source for many marine creatures, including sea turtles and some fish species. They also help to control the population of tiny marine animals by feeding on them, and their waste products contribute to the nutrient cycle in the ocean.

However, jellyfish populations can sometimes explode and become a nuisance. This phenomenon mostly occurs when their natural predators are eliminated from the ecosystem or when water conditions, like temperature and salinity, are conducive for jellyfish growth. In cases where jellyfish populations reach excessive levels, they can clog fishing nets and interfere with other human activities in the ocean.

Jellyfish really are stunning creatures of the ocean. They’re diverse, with many different species, and are essential to the marine ecosystem. While they can sometimes become a nuisance, they’re vital to the ocean’s food web and nutrient cycle. Studying jellyfish can give us a greater understanding of the complex and interconnected systems that make up our oceans.

Practical Tips for Creating Perfect Academic Papers

Developing writing skills is crucial for your academic success regardless of your major. Check out these tips we provided for improving your writing. But if you aren't fond of writing, you can easily hand it to professionals by saying, ‘ do homework for me .’

Search for Samples or Examples

To improve your writing, analyze examples of well-written biology essays or research papers. Although not all online samples are perfect, they can still provide insights into what works and what doesn’t. However, avoid plagiarism and ensure your paper is original by presenting fresh ideas and a unique perspective. 

Read Whenever You Can

Develop your writing skills by reading widely and extensively. Look for biology papers in scientific journals, websites, or books. Don’t forget to take notes on interesting points that you can use in your papers later.

Practice Makes Perfect

Don’t expect to write a perfect paper on your first try, so take every opportunity to practice your writing. Find a mentor if needed and use online resources to learn from your mistakes and improve your skills.

Always Organize Your Writing Process

Organize your work process instead of waiting for inspiration by defining stages, scheduling time for each task, and eliminating distractions. Don’t wait for mood to write an essay about biology; use different strategies to overcome writer’s block.

Proofread and Get Other Feedback

It’s hard to assess your own work accurately. Seek feedback from peers or instructors to identify strengths and weaknesses to improve upon. Don’t wait for your professor’s feedback to know if your biology essay is good.

How to Write a Biology Essay

By: Tasha Kolesnikova

Studying natural sciences and biology in particular, you’ll deal with essays as one of the ways to assess your knowledge and skills. Professors believe that this assignment helps students to develop their skills regardless of the major you pursue. Future biologists should organize their ideas in a structured and transparent manner, using reliable sources and persuasive examples to support your perspective. Even if you’ll work in laboratories, you will deal with written reports.

What is a Biology Essay?

Select the topic for your essay, select a research question, create an outline, essay introduction, thesis statement, essay conclusion, citation and references, look for samples, practice your writing, plan your writing process, ask for feedback, appropriate language for complexity science, writing services, editing proofreading services, what is biology as science, what is the importance of biology in our life, major concepts and topics in biology.

Don’t worry if you don’t have enough experience and doubt your ability to deliver a perfect paper. We have prepared useful tips to help you write a killer biology essay and deliver it on time.

A biology essay is a piece of student writing where you provide arguments and ideas concerning a particular biological topic.

There are various academic essay types, and you can adhere to one of them. For example, you can write a descriptive paper explaining a biological subject. Or an argumentative paper, providing evidence to support your point of view. One of the most common essay types is a cause and effect piece where you explain the reasons and the consequences of some events. You can also come up with the “how-to” instruction or a detailed analysis . The concrete type depends on your professor’s requirements and your preference.

How to Write a Good Essay in Biology

Some people consider writing an art process. However, it is a work that requires your time and effort. You should organize the whole process if you want to get the desired result. There is a step-by-step instruction to follow.

If you want to get a good grade, it is important not only to make your paper informative but also enjoyable. It depends on the topic you choose. And it is crucial to stay on something that you wish to explore. Try to find something you want to investigate.

It is not easy because you may have many ideas in your head, but once you start writing, they disappear. That’s why studying at college, you should always have a notebook at hand, to write down things that come to mind.

The most effective way to select the topic is a brainstorming technique. Let your brain provide you with 30-50 decent options, and then research to create the shortlist with the best ones.

Writing a biology essay, you should use a scientific approach. Come up with a research question you want to answer in your paper. Of course, you shouldn’t choose something too complicated that it is impossible to work through in terms of one piece. It shouldn’t be too obvious as well. Connect your research question with the topic.

Starting a paper, you should have a clear plan to follow. Most student papers have a 5-paragraph structure with specific instructions. It would be almost impossible to keep the main idea and develop good arguments if you just begin. It would help if you started with the outline to keep it in mind when writing.

Don’t worry about how it looks. Nobody will check your plan (if your professor didn’t ask you to deliver it as well). You can organize your thoughts the way you like. Sketches, paints, mind maps, and so on. Use anything you need to make your paper structured. Get rid of all ideas that don’t work for your research question, even if they seem reasonable. You may use them in another paper.

Whenever you need it, you can make some amends and correct your outline.

It is the first paragraph that is intended to attract the readers’ attention. Writing it, you should consider your target audience.

If you’re preparing a paper for newbies, you should provide some basic knowledge, interesting facts, and statistics to introduce the topic.

However, the experienced audience may find such an introduction a bit boring. They already know the main point, and they have a single question: why is this topic important? So, you should provide them with an explanation of why you have chosen this issue and which directions you see for further development.

The introduction finishes with the thesis. It is your research question or the statement you’re going to develop in the body paragraphs. In other words, you should synthesize the overall essay, meaning just in one sentence. It will explain to your readers what the paper is about and your point of view. Without a strong thesis statement, the whole piece becomes useless, given that the audience cannot understand your position.

Body paragraphs are the essay core because they are most voluminous and informative. Once you’ve grabbed the readers’ attention, you should provide them with food for thought.

In a classic 5-paragraph essay structure body takes 3 paragraphs. Each of them is intended to reveal just one idea. You need to provide a short thesis, an explanation, and an example to illustrate your point.

It would help if you were very attentive in writing the essay body because it is easy to lose your way. This is where your outline may be helpful.

Once your readers finish the paper, they have a question “So what?” If you leave them with it, you’ll fail. Your task is to provide an answer to explain how the audience can use the information you’ve written in the body.

Don’t use any new data; just conclude the thoughts you’ve already declared. Are they important in any sense? Can readers conduct their research and gain more insights? Should they be more attentive to environmental issues?

You’ve written a paper with a particular goal (except for getting a good grade), so show your readers whether you’ve achieved it.

Most academic papers require authors to provide additional information. For example, a list of references you’ve used. It is impossible to write a biology essay without data from books, websites, research papers, and so on. And if you use any journal or other source, you should cite it correctly since, in the other case, your piece would be considered plagiarism.

You should adhere to a particular citation style. When it comes to biology, the academic society uses the APA and the CSE format. Make sure you know what style your professor prefers. You also need a relevant guide with all requirements to follow.

Some Essay Tips for Successful Writing

Whatever major you pursue, you’ll deal with written assignments that affect your academic performance. That’s why you need to develop your writing skills. Here you’ll find some actionable tips to follow.

If you want to write well, you should read well. There are various modern sources where you can find many biology papers. It goes about scientific books and journals, specific web-portals. Don’t undervalue the fiction literature as well. You need to understand how other people write and to learn from them.

Once you’ve noticed something interesting that is worth your attention, write it down. You may use these notes in your future writings.

Coming up with a perfect piece, you should understand what the “perfect” stands for. Please take a look at some essays or a research paper example and analyze them.

It doesn’t mean that all samples that are published online are excellent. They have advantages and disadvantages, and you should mention them.

However, don’t copy and paste these samples. Your paper should be unique, and it goes not about paraphrasing some sentences only. The ideas and concepts you use should be fresh as well. Even if you’re just a student, without tremendous research opportunities, you may look at the issue from an interesting angle. Essay samples will show you the right direction.

You shouldn’t expect that your first paper will be outstanding. You have to submit dozens of poor essays until you succeed. It means you should use any opportunity to write something. Whether it is a note, a blog post, a lab report, or an experiment description, you should master your ability to formulate thoughts and choose the best words to convey your ideas.

Don’t leave these texts without attention since you can’t become a better writer if you don’t know your mistakes. Find a mentor who will provide you with essential tips. There are many useful resources online, and you can always hire a professional tutor who will support you.

You can’t sit and wait for the inspiration. Your professor won’t understand the excuse that you aren't in an appropriate mood to write a paper. Therefore you should be able to organize yourself and the work process.

Firstly, define stages, e.g., the research stage, the introduction writing, and so on. Think about how many times you’re going to devote to each of them and include these tasks in your calendar. You can use different strategies, starting with the most complicated part, or, vice versa, from the easiest one. It doesn’t matter if you’re able to provide a good result.

It is also important to get rid of all distractors in advance. Switch off your smartphone and make sure you have anything you need to come up with a paper. It won’t leave the space for procrastination.

People are usually biased when it goes to work. You can’t define for sure whether your biology essay deserves an A-grade. And it would be the wrong decision to wait until your professor spoils your academic performance. You can then discuss your writing with your friends, fellow students, instructors at the college club. If you think someone can provide you with professional assistance, ask for it. Feedback will show your strengths to focus on and weaknesses to work out.

Writing a research paper, you should use a language of scientific thought to explain your ideas. Think about the audience and its level of education. If your paper is full of specific terms, most readers won’t understand it. However, it should not be too simple at the same time since you’re a future biologist and should speak this language at a decent level.

It is also important to know all requirements and follow them. Each paper has its features, so make sure you understand the essay, analysis paper, or a lab report format before writing.

Biology is a science that studies our life in different ways. Students learn about organisms and living creatures that inhabit the planet, their functions, behavior, interaction, and their individual and historical development.

Modern biology covers various sub-topics, such as virology that studies viruses, botany that studies plants, the anatomy that studies the human’s body, etc. Some students choose a particular direction to work in, but all these subjects are united. It would be best if you had morphology and genetics knowledge to succeed with microbiology, and vice versa.

Writing a biology essay, you should think about their final purpose. Some papers are intended to provide people with a fresh look, e.g., when you find exciting information and want to share it with your colleagues. At the same time, you can write a paper for people who don’t have solid biology knowledge. These essays will be very different, so you need to approach this task with all responsibility.

Biology knowledge is important regardless of your career plans. Many facets point to this. First, this science is mainly studying life that is surrounding us. Second, it is important to have an understanding of how all organisms interact with each other. And the next reason that is no less important is the diversity of our life. Thanks to biology knowledge, people treat illnesses, improve food quality, and take care of the whole ecosystem.

It is the study of life that helps people shape the world and provides them with answers that explain why things happen.

Studying biology, you’ll deal with the following topics:

• Cellular structure and function;
• Evolution and natural selection;
• Heredity and genetics;
• Ecosystems and interdependence.

Many concepts are accepted by modern biology science. These are ideas and understandings that professors want you to remember. For example, all organisms share a standard set of important life processes. It goes about movement, respiration, reproduction, nutrition, and others. All organisms use the same genetic system to maintain continuity. The next essential concept is about species that arise, change, and become extinct over time. Diverse adaptations are the reason why evolution results and ensures survival.

Writing your paper, you should show your knowledge and understanding of significant biology concepts and topics. It would be an excellent platform to create powerful, evidence-based content.

Extended Essays in Biology

Choosing a topic

Choosing a Topic

Biology is the science that deals with living organisms and life processes. A biology EE should incorporate biological theory and emphasize why it is relevant today.

The topic must relates specifically to biology. Many topics can be approached from different viewpoints, but for an EE in biology the treatment of the topic must be clearly biological. For example, an EE in an interdisciplinary area such as biochemistry will, if registered under the subject of biology, be judged solely on its biological content.

Disease, for example, could be considered through many different lenses. A biology paper about diseases would focus on their impact on particular organisms or life processes, and not on medical treatment, or the economic effects of the disease on society.

Approaches to research

Primary Research

Essays in biology may be based on data collected by the student through:

Essays that involve lab work, or fieldwork, should include a clear and concise description of the experimental procedure. Students taking an experimental approach must also consult secondary sources.

Secondary Research

Students can base their essays on data or information obtained from literature (secondary studies). However, in this case they should use the data in an original way. Essays that simply restate facts or data taken directly from the sources are of little value.

Biology Sources

Even students doing primary research will still need to reference secondary sources. And students relying entirely on secondary sources will need to find sources not only of written information but also experimental data which they can analyze.

Writing the Essay

An essay in the sciences requires is more than just generating and presenting data. Analysis of the data is also essential. The main body of the essay should consist of an argument or evaluation based on the data or information presented . You can gather your own data through a variety of methods, or rely on secondary data. You should use graphs, tables, or diagrams to point out the significance of your findings.

You should ensure that the main body of the essay is well structured and has an obvious logical progression. You can use numbered and headed paragraphs to impose a clear structure. Your evaluation should show that you understand the the data they have collected and its significance to the world.

In your analysis, you should also describe and explain the limitations imposed on the research by factors such as

• the suitability and reliability of the sources accessed
• accuracy and precision of measuring equipment
• sample size
• validity and reliability of statistics

Students  should also consider biological limitations such as:

• those arising from the problem of repeatability and control when using living material
• the difficulties of generalizing from research based on a single type of organism or environment.

Exceptions for Safety and Academic Honesty

Safety and Ethics in Choosing a Topic

In all cases where human subjects are used as the basis for an investigation, clear evidence of informed consent must be provided in accordance with the IB guidelines.

Some topics may be inadmissible because their means of investigation are unethical. For example, investigations that:

• are based on experiments likely to inflict pain on, or cause stress to, living organisms
• are likely to have a harmful effect on health, eg culturing micro-organisms at or near body temperature (37°C)
• involve access to, or publication of, confidential medical information.

Some topics may be unsuitable because of safety issues. Adequate safety apparatus and qualified supervision is required for experiments involving dangerous substances such as:

• toxic or dangerous chemicals
• carcinogenic substances
• radioactive materials.

Other topics may be unsuitable because the outcome is already well known and documented in standard textbooks.

Essays About Biology: Top 5 Best Examples and 6 Prompts

Writing essays about biology can be difficult because it’s composed of many subtopics. Check out this article for our top essay examples and writing prompts .

Biology came from the Greek words “bios” (life) and “logos” (study). It’s why biology is the study of life or living organisms . Aside from being a natural science, it also has consolidated themes, such as cells making all organisms . Because it’s a broad topic , biology is divided into specialized fields such as botany, genetics, zoology, microbiology, medicine, and ecology. 

Biologists consider living beings ‘ origin, evolution, growth, function, structure , and distribution. It’s a comprehensive subject, so there are many things you can write about in your essay. However, at the same time, you might find it challenging to focus on just one area. 

Below are examples to give you an idea of how to write your essays about biology :

1. Essay About Biology by Kelli Wilkins

2. my interests in biology by anonymous on essaywriting.expert, 3. essay on the importance of study of biology by akhila mol, 4. what biology means to me by anonymous on studymode.com, 5. how my biology teacher changed my perspective of learning the subject by sankalan bhattacharya, 1. biology in my everyday life, 2. something i realized because of biology, 3. my memorable biology class experience, 4. genetics’ role in people’s diseases, 5. my experience during the pandemic, 6. biology and health.

“Studying Biology is important for a number of reasons, but in particular because it is used in every field. If we did not have a good understanding of Biology then nobody would be able to understand how bodies work, and how life on earth functions.”

Wilkins shares her desire to study anatomy, a branch of biology, and expounds on what makes biology an essential field. Because biology lets people know more about the world, she digs into why she’s interested in anatomy, specifically to find ways to cure illnesses and develop technologies to discover new treatments. She ends her essay by relating biology to the existence of doctors and hospitals. 

“It is known that education plays an important role in the life of any individual. It gives an opportunity to develop personality and gain specific skills, to get profound knowledge and experience in order to apply them practically in the future. As for me, my major goal is to study Biology in order to get appropriate knowledge and skills required for my future profession.”

The author shares why they want to study biology, referring to the human body as the “perfect machine” and curious about how it performs each of its systems’ functions. The writer also mentions how biology is critical to their future profession. They aim to help people with their health problems and relay their desire to research the brain to find more data on it. 

“The study of biology owes great significance in human life, because man for its day-to-day requirements is dependent on plants and animals either directly or indirectly.”

Mol lists seven reasons why humans need biology in their daily lives. Her list includes health, diseases, agriculture, horticulture, food, animal breeding, and entertainment. She expounds on each point and how they affect a man during his time on Earth. She explains each relationship in a simple manner that’s easy to understand for the readers.

“Without biology, we would have no idea about an organism ’s makeup, or the most basic unit of life, a cell… Biology influences me in many ways. Biology influences me by teaching me why to take care of the environment, why I am to take care of my body, and by giving me a better overall view of all scientific areas of study.”

In this short essay, the writer lists down reasons why biology is essential. These reasons include taking care of the environment, one’s body, and others. The author also expounds on their reasons by presenting facts supporting biology’s importance to the world and human lives.

“He told that the syllabus may be a good way to prepare for an exam but our knowledge should not be limited to any syllabus and the questions that were asked in the examination were related to the topic only. He told that if we try to know things in detail and understand them properly then the interest in the subject will develop, otherwise, students will not treat the subject as a subject of their choice. 

Bhattacharya shares his experience with a teacher with a unique teaching style. His Biology teacher from Class 7, before the era of the internet, don’t just carry one book to get all his lessons from. Instead, he has a notebook with the collated information from many books to teach his class. 

Bhattacharya’s teacher taught them things that were not in the curriculum, even if following the curriculum would give him higher points in his evaluation. He only wanted his students to learn more and share with them why learning differs from just knowing.

6 Prompts for Essays About Biology

You don’t have to be a biology student to write an essay about the subject. If you’re looking for easy prompts to write about, here are some to get you started:

If mitochondria are the powerhouse of the cell, who is the powerhouse of your classroom? Your home? Relate a biology topic to a similar structure in your life, then explain why you think they are the same. 

For instance, you can compare your mother to mitochondria which generate the energy needed to power a cell. The cell being you. You can say that she gives you energy every day by being there and supporting you in whatever way she can. This prompt bodes for a creative and intriguing essay.

Relay a lesson you learned from biology and how it perfectly explained something you were once hesitant about. Such as being insecure about your big ears – only to know from a biology trivia that ears never stop growing. You can then share how this help lessen your insecurity because you now know large ears are normal. 

Do you have a memory you won’t forget that happened during biology class? Narrate this story and explain why it’s something that left an impression on you. To give you an idea , you can talk about the first time you dissected an animal, where you first realized how complex organisms are and that they are made of many systems to function, no matter how small.

Gene action and heredity are evolving. If you have a genetic illness or know someone who has it, you can share your experience. Then explain what your genes have to do with the disease. Is it something you got from your parents? Did they inherit it from your grandparents? Finally, you can add what your parents’ and grandparents’ lives were like because of the disease.

Virology, another branch of biology, studies viruses and viral diseases. A recent example is the coronavirus pandemic, where more people realized the importance of knowing a virus’ origin, structure , and how they work. Write an essay where you explain how the pandemic operates, such as why people should wear masks, social distance, etc.

For this essay, you can write about how biology helps you care for your health. For example, you can include how biology helped doctors give you the appropriate diagnosis, how you had the opportunity to have the proper treatment, etc. 

If you want to write on a related topic , here are essay topics about nature you can consider for your next essay.

Biology papers give us an opportunity of understanding forms that are complex in life. This, therefore, means you will have the chance to fully understand the plants as well as the animals found in the ecosystem. People are given assignments on biology so that they can fully research and have knowledge concerning the components of nature. An essay on biology also assists people in how to care for and tend to themselves. These biology papers also assist in fully understanding how the world and humanity are related. An essay on biology will, therefore, assist in answering queries and issues related to biology. The tips from our academic essay writing service may help a person to make the work professional without errors and mistakes. A primary element to keep in mind when writing biology papers is always to have a biology essay draft that will assist you all through the writing process. Biology essay topics need to be detailed so that they can be differentiated from other types of papers.

The topics of the biology papers determine the points that will be used in the article. This, therefore, means that the biology essay writing guide is dependent on the topic selected . Ensure that you fully understand what the biology essay writing expects from you and create a biology essay outline that will assist you in preparing an excellent piece. Biology essay outlining assists in the construction of detailed articles. Below are biology essay topics that one can use in biology essay writing.

Biology essay topics

• Are vaccines necessary in our system?
• Omnivore’s plants
• How did the dinosaurs just disappear?
• Did the evolution start from the monkeys?
• Which are the most intelligent animals on the face of the earth?
• Why do the male seahorses often carry the offspring?
• How were the wolves domesticated?
• The genetic mutations in plants and animals.
• How the albino animals are different; is this trait also shared in plants and humans?
• The process of aging in humans.

These are some of the good biology essay topics that you can use to produce an article that is standard.

Biology essay structure

The outline for a biology essay gives you clear guidelines on how to go about writing the article. The biology essay draft should go in line with the topic that the writer has chosen.

The biology essay outlining is as illustrated below:

1. The title

• The title page offers clear indications of the biology essay focus.
• The title should be precisely phrased and at the same time based on the hypothesis.
• Avoid jargon for the title to look professional.
• The title should also give the reader a quick understanding of the topic.

2. The content page

This page is located at the beginning of biology papers after the abstract and the title pages. The page shows the numbers as well as the subsections of the essay on biology.

3. The research question

The topics for a biology essay determine the research questions to be used. The research question shows what the article is trying to establish. Keep in mind that the question is not the same as the title.

• The question in motion should be highlighted in the introduction. The content page will give the reader an understanding of the article.
• The question should introduce new ideas as well.

4. The introduction

The biology essay introduction is the most crucial part of the article, as it will determine whether the readers will want to read more of the piece or not.

• The introduction for a biology essay should illustrate what is being argued in the article.
• For an introduction to be successful, the contents need to be brief and accurate.
• Another professional way how to start a biology essay introduction is by illustrating how you reached the focus of the research.
• The introduction should also contain the references that were accessed.
• What might be revealed in the study should also be highlighted in the opening section.

5. The investigation

The study section gives you the chance of illustrating how the data was selected as well as its reliability.

• You need to clearly explain, describe and justify the choice of collecting primary data.
• Don’t forget to state the sources of the experiments. The method used should be detailed. Someone would want to repeat the same procedure.
• Ensure that the investigations are ethical and not cruel.

6. The analysis

• The body is the meat of the literature essay. The body covers most of the article. A common way how to write a biology essay body is by using at least three paragraphs.
• The biology essay tips need to be relevant to the research question being discussed. The points should also give assertion to the reader.
• Highlight the biology essay prompts as well. Elaborate on how the ideas have been used to support the question in the essay on biology.
• For an effective essay on biology writing, discuss each point in its paragraph. This technique will give you the chance of exhausting the points.

7. The biology essay conclusion

The end of the article should be firm and sum up the whole article. The conclusion is a formal way how to conclude a biology essay. The conclusion restates the points for emphasis and makes the final argument clear. This section also gives you the chance of drawing connections between the points and questions being discussed. The conclusion for a biology essay also gives room for you to show your engagement with the essay on biology on a personal ground. The conclusion should be in a position of reformulating a new hypothesis as well as comparing the content to the secondary sources used. You can finish up the biology essay by stating the significance of the statistical tests done.

8. The references

Making citations is an essential issue in biology papers. There are quite some formatting and citation styles ranging from APA to MLA.  You should, therefore, be keen on the style specified. Referencing styles depends on the academic discipline that one is in. For instance, APA is used in psychology, education, and sciences

Archetti M 2000. The origin of autumn colors by coevolution. Journal of Theoretical Biology, 205: 625–63

9. Sources for essay choice

Sources can either be secondary or primary. The primary source refers to any work that can be accessed originally. The secondary source refers to the works that have been original, but have been produced by another person. Examples of secondary sources include books , encyclopedias, and journals among other recreated works. You can use both the primary and secondary data to make your biology paper a success.

10. Finalizing the Essay

Once the essay on biology has been written, a revision is necessary to ensure the content is in order. A standard method of review is proofreading. Proofreading gives you the chance to analyze your work and correct errors that are avoidable.

What I learned from messing up my biology extended essay

Each year we invite IB alumni to share their experiences, interests and advice with our global community in the  graduate voices  series. We welcome Diploma Programme (DP) graduate Lim Hui Yuan to share some tips and advice to DP students completing their extended essays after completing her DP education at Hwa Chong International School .

By Lim Hui Yuan

I’m sure all the current and past IB students know the hardship of completing an Extended Essay (EE). And for those who are not familiar with EE, it is actually “ an independent, self-directed piece of research ”, which culminates into a 4,000-word paper.

To many (including me), EE was a real boot camp training because of the effort and tenacity it requires one to possess. Well, it was quite daunting a time for me, BUT—I have to admit that I learned a lot from messing up my project. Looking back, the nine months I spent on my EE was indeed an endurance experience.

Here are my takeaways from almost failing my Biology EE. Some of them might be relevant to other EE subjects, but they mainly revolve around the challenges I personally faced.

Knowing what you’re interested in isn’t always that easy

They always say, “follow your heart”

“Pick a project topic that you are interested in.”

Sometimes, we might not even know what our heart wants and where our interests actually lie. We students face a dilemma when choosing an EE subject or topic in the same way we are confused when standing at the junction of deciding which university path to choose.

There is a plethora of topics that we could work on, but not all of them could keep us motivated for more than half a year. I chose, “The Efficacy of Natural Plant Extracts and Commercial Disinfectants in Reducing Bacterial Growth.”

I like to think of it like becoming a gardener. Your project starts off small, you have to nurture it, and once the research topic is settled, it just keeps growing. In the end, you’ll have an EE that has grown from just a tiny seed into a big plant you are really proud of.

Nevertheless, I came to realise that no matter what topic you choose, as long as you pour your heart into it, you will not regret the outcome.

Asking yourself, “ why do I want to do this project?” helps to keep you on the right track (even if the answer was “to get a good grade”).

Failing is more common than succeeding

After diving into my biology EE, I realised how easy it was to carry out experiments in class compared to conducting your research project. There’s no lab manual you can simply refer to. Instead, you have to create your own recipe , adapting from previous work. And since it’s your own custom-made experiment, you can never predict how the results will turn out.

As much as you try to fix the controlled variables, it seems like you can’t control the outcome of the study.

In my case, I expected some of the plant extracts to show antibacterial properties. However, I underestimated how mischievous the bacteria can be, contaminating all my plant samples.

I took the success of the experiment for granted.

This bump went on for over five months. At one point, I was so traumatised by the lack of progress that I couldn’t bring myself into the lab. Frustrated and drained, I was on the verge of giving up.

Here’s when you should take a breather to flush away the negative emotions and reset everything—including your impression of the project itself.

Learn to move on

Just as the wise Ryan Higa mentioned, “ here’s a bridge; now, get over it ”.

Whatever will happen has happened and all you can do is to move on.

After getting yourself ready for a fresh start, you should turn on troubleshoot mode and make amendments to your procedures. Try to pinpoint the problem and then search for plausible solutions to tackle it. The trial and error method is the only way!

Imagine beginning to piece a puzzle together; you usually know what the big picture looks like first before connecting the parts. The same applies to your EE. Plan ahead.

Set mini-deadlines as you draft your action plan. The timeline is essential so that you don’t feel too overwhelmed by a load of work (especially when you have a month left to write your EE after getting your results, which was exactly my case).

Be careful not to be too optimistic with the progress of your experiments. I expected and planned that mine would take at most two months to finish, but I completely neglected some time factors such as time needed for the bacteria to incubate, to make the agar plates, the opening hours of the lab (which leaves me only a few hours after school), and of course , failures.

You may have a supervisor to nag you about your EE progress. However, once you’re out of high school, nobody will be there to alarm you and snoozing off will cost you more than just your grades.

You’re not alone on this

If it weren’t for my EE supervisor and friends, I would’ve given up.

My EE supervisor kept encouraging me and taught me how to endure an initial lack of results, and I’ve learned since then that this is actually a norm of scientific research . One of my best friends, who was also doing a biology EE, took his time to teach me how to write a biology EE amidst his busy schedule (you know who you are, thank you!).

Remember to discuss your difficulties to your advisor or friends; they’ll be your pillar of support.

EE is not only here to prepare you for undergraduate research, but also provide a resilient attitude for life, in general.

Honestly, I’m quite grateful that I faced so many problems during the process. It feels like playing a game with many obstacles and overcoming each hurdle leads you to a higher-level ranking. I am, by no means, a “Legend”, but I’ve certainly passed the “Rookie” level.

P.S. Remember to pat yourself on the back after completing your EE. After all, you’ve shed blood, sweat and tears into raising your seedling into a plant.

Lim Hui Yuan is a graduate of Hwa Chong International School , Singapore. She is currently pursuing her degree in science, specifically a major in Molecular Biology and Biotechnology, at the University of Hong Kong. She likes to experiment with new things and loves dancing and cooking. Also, you can find her binge-watching dramas most of the time.

How to Write a Biology Essay Like a Pro

Table of Contents

Writing effectively in the scientific realm is integral to any decent education. However, it is frequently ignored in favor of more theoretical topics in introductory science classes. 

It is also crucial to have excellent presentation skills if you want to achieve any level of success in the sciences. Moreover, graduate students must write several scientific papers to enter the scientific workforce as a professional.

It is, therefore, crucial that students work with research paper writing services to do my statistics homework and have a firm grounding in scientific writing to advance in their academic careers.

Most biology students are so preoccupied with the scientific method that they neglect developing their writing skills. As a result, the first step is to tell you not to skip the step of writing a quality scientific paper.

Writing essays in the sciences is not the same as in an English or art class. 

Such factors can complicate the already challenging task of creating a scientific paper. That is, more so when dealing with novel or technically complex material. 

However, a good essay can help you learn more about the subject as you have to write and submit an article that makes sense and is supported by research. Here are six useful tips for writing an excellent biology essay.

1. Pick an essay topic

Your work must be valuable and interesting to the reader to score highly. It’s up to you to decide on a subject. For starters, it is essential to maintain focus on a topic you are eager to investigate. Determine what it is that you would like to learn more about.

While you may have a lot of ideas floating around in your head, you might find that they evaporate once you put pen to paper. This is why, while you study for your college courses with the help of a persuasive essay writer , who you can find by checking out objective essay writing service reviews online, you should always have a notebook at hand. Here you can jot down any ideas that come to you.

Using a brainstorming method is the most efficient means of choosing the topic. Try to generate 30–50 viable choices. Based on your study, narrow that down to a manageable handful.

2. Develop a plan

To get started on a paper, you need to establish a plan. The standard format for student essays is five paragraphs, although instructors may provide additional guidelines. If you just start writing, you probably won’t be able to keep the basic idea and build solid arguments.

The outline will serve as a guide as you write, so it’s best to start with that. Ignore aesthetic concerns. No one would bother if your professor didn’t specifically ask for a copy of your plan. 

Artistic mediums such as sketches, paint, and mind maps can prove very valuable. You can use whichever tools you like to give your document structure. 

Eliminate any plausible but unhelpful concepts that don’t relate to your study subject. You can repurpose them in another one of your papers. The outline can be revised and updated as much as necessary.

3. Introduction

In this section, your readers will learn the basics of the topic at hand. Here, you should briefly review any relevant prior research.

The essay’s purpose needs to be stated explicitly so that your readers understand where the narrative is going. Your introduction should be well-organized and brief (no more than two pages).

The body comprises the major conclusion drawn from your study or your own view or stance on the matter. This section needs to describe the experiment in-depth, highlight the most important results, and explain how and why those results were obtained.

Writers and students penning essays based on their personal opinions should back up their claims with research and theory. Citations and references are required as a result.

Students could also include relevant charts, graphs, and pictures. The illustrations must have clear titles and explanations. The axis of the graph must also be described.

5. Conclusion

Clearly outline the main arguments and explain your thinking. 

Additionally, you can suggest new lines of inquiry into the matter, which may lead to the discovery of hitherto unknown answers. It’s crucial to ensure your conclusion is structured similarly to your introduction.

The last paragraph should be a short restatement of its primary themes. Remember, the latter section of your paper should be just as concise as the first.

Refrain from passing off someone’s writing as your own. Although there are other accepted styles for doing this, the American Psychological Association (APA) format is the most popular. If you need assistance locating credible references, any the best research paper writing service can help.

6. Relevance is key

The topic you choose should have everything to do with the material you’re discussing in your essay. If you don’t, it’ll seem haphazard and awkward or, at best, forced into the report. If you don’t have a firm grip on your scientific subject, it will reflect poorly on your overall essay.

To capture the reader’s interest in your paper, start with a surprising or humorous fact.

The information you give can either back up your essay’s thesis or serve as a component of the body of evidence you describe in your expository paper.

Simply being a good writer isn’t enough to create a fantastic essay. As you prepare to write your biology paper, these are a few things you should keep in mind.

Review Essays for the Biological sciences

A review essay for the biological sciences serves to discuss and synthesize key findings on a particular subject. Review papers are helpful to the writer and their colleagues in gaining critical awareness in specialized fields that may or may not be their own.

This guide explains what a review essay is and identifies several approaches to writing a review essay. Although much of the information is geared directly to the biological sciences, it is generally applicable to review essays in all fields.

What is a Review Essay?

A review essay is a synthesis of primary sources (mainly research papers presented in academic journals) on a given topic. A biological review essay demonstrates that the writer has thorough understanding of the literature and can formulate a useful analysis. While no new research is presented by the writer, the field benefits from the review by recieving a new perspective. There are several approaches one may take when writing a biological review:

A State of the art review

A state of the art review considers mainly the most current research in a given area. The review may offer new perspectives on an issue or point out an area in need of further research.

A Historical review

A historical review is a survey of the development of a particular field of study. It may examine the early stages of the field, key findings to present, key theoretical models and their evolution, etc.

A Comparison of perspectives review

A comparison of perspectives review contrasts various ways of looking at a certain topic. If in fact there is a debate over some process or idea, a comparison of perspectives review may illustrate the research that supports both sides. A comparison of perspectives review may introduce a new perspective by way of comparing it to another.

A Synthesis of two fields review

Many times researchers in different fields may be working on similar problems. A synthesis of two fields review provides insights into a given topic based on a review of the literature from two or more disciplines.

A Theoretical model building review

A theoretical model building review examines the literature within a given area with the intention of developing new theoretical assumptions.

Key Considerations for Writing a Biological Review Essay

This guide will inform you of certain things not to miss when writing a review essay. It will also give you some information about using and documenting your sources.

Keep your focus narrow.

When writing a review essay it is important to keep the scope of the topic narrow enough so that you can discuss it thoroughly. For example a topic such as air quality in factories could be narrowed significantly to something like carbon dioxide levels in auto manufacturing plants .

A good way to narrow your focus is to start with a broad topic that is of some interest to you, then read some of the literature in the field. Look for a thread of the discussion that points to a more specific topic.

Analyze, synthesize, and interpret.

A review essay is not a pure summary of the information you read for your review. You are required to analyze, synthesize, and interpret the information you read in some meaningful way.

It is not enough to simply present the material you have found, you must go beyond that and explain its relevance and significance to the topic at hand.

Establish a clear thesis from the onset of your writing and examine which pieces of your reading help you in developing and supporting the ideas in your thesis.

Use only academic sources.

A review essay reviews the academic body of literature—articles and research presented in academic journals. Lay periodicals such as, Discover , Scientific America , or Popular Science , are not adequate sources for an academic review essay.

If you are having trouble finding the academic journals in your field, ask one of your professors or a reference librarian.

Document your sources.

The material that you discuss in a review essay is obviously not your own, therefore it is crucial to document your sources properly. Proper documentation is crucial for two reasons: 1. It prevents the writer from being accused of plagiarism and 2. It gives the reader the opportunity to locate the sources the writer has reviewed because they may find them valuable in their own academic pursuits. Proper documentation depends on which style guide you are following.

Quote sparingly and properly.

No one wants to read a paper that is simply a string of quotes; reserve direct quotations for when you want to create a big impact. Often times the way a quote is written will not fit with the language or the style of your paper so paraphrase the authors words carefully and verbage as necessary to create a well formed paragraph.

Choose an informative title.

The title you choose for your review essay should give some indication of what lies ahead for the reader. You might consider the process you took in narrowing your topic to help you with your title—think of the title as something specific rather than a vague representation of your paper's topic. For example the title Wastewater Treatment might be more informative if rewritten as The Removal of Cloroform Bacteria as Practiced by California's Municipal Water Treatment Facilities .

Consider your audience.

More than likely your audience will be your academic peers, therefore you can make a couple assumptions and choose a writing style that suits the audience. Though your audience may lack the detailed knowledge you have about your topic, they do have similar background knowledge to you. You can assume that you audience understands much of the technical language you have to use to write about your topic and you do not have to go into great detail about background information.

Elements of a Review Essay

This guide explains each section of a review essay and gives specific information about what should be included in each.

On the title page include the title, your name, and the date. Your instructor may have additional requirements (such as the course number, etc.) so be sure to follow the guidelines on the assignment sheet. Professional journals may also have more specific requirements for the title page.

An abstract is a brief summary of your review. The abstract should include only the main points of your review. Think of the abstract as a chance for the reader to preview your paper and decide if they want to read on for the details.

Introduction

The introduction of your review should accomplish three things:

• It may sound redundant to "introduce" your topic in the introduction, but often times writer's fail to do so. Let the reader in on background information specific to the topic, define terms that may be unfamiliar to them, explain the scope of the discussion, and your purpose for writing the review.
• Think of your review essay as a statement in the larger conversation of your academic community. Your review is your way of entering into that conversation and it is important to briefly address why your review is relevant to the discussion. You may feel the relevance is obvious because you are so familiar with the topic, but your readers have not yet established that familiarity.
• The thesis is the main idea that you want to get across to your reader. your thesis should be a clear statement of what you intend to prove or illustrate by your review. By revealing your thesis in the introduction the reader knows what to expect in the rest of the paper.

The discussion section is the body of your paper. The discussion section contains information that develops and supports your thesis. While there is no particular form that a discussion section must take there are several considerations that a writer must follow when building a discussion.

• A review essay is not simply a summary of literature you have reviewed. Be careful not to leave out your own analysis of the ideas presented in the literature. Synthesize the material from all the works—what are the connections you see, or the connections you are trying to illustrate, among your readings.

A review essay is not a pure summary of the information you read for your review. You are required to analyze, synthesize, and interpret the information you read in some meaningful way. It is not enough to simply present the material you have found, you must go beyond that and explain its relevance and significance to the topic at hand. Establish a clear thesis from the onset of your writing and examine which pieces of your reading help you in developing and supporting the ideas in your thesis.

• Keep your discussion focused on your topic and more importantly your thesis. Don't let tangents or extraneous material get in the way of a concise, coherent discussion. A well focused paper is crucial in getting your message across to your reader.
• Keeping your points organized makes it easier for the reader to follow along and make sense of your review. Start each paragraph with a topic sentence that relates back to your thesis. The headings used for this guide give you some idea of how to organize the overall paper, but as far as the discussion section goes use meaningful subheadings that relate to your content to organize your points.
• Your thesis should illustrate your objectives in writing the review and your discussion should serve to accomplish your objectives. Make sure your keep your discussion related to the thesis in order to meet your objectives. If you find that your discussion does not relate so much to your thesis, don't panic, you might want to revise your thesis instead of reworking the discussion.

Conclusions

Because the conclusions section often gets left for last it is often the weakest part of a student review essay. It is as crucial a part of the paper as any and should be treated as such.

A good conclusion should illustrate the key connections between your major points and your thesis as well as they key connections between your thesis and the broader discussion—what is the significance of your paper in a larger context? Make some conclusions —where have you arrived as a result of writing this paper?

Be careful not to present any new information in the conclusion section.

Here you report all the works you have cited in your paper. The format for a references page varies by discipline as does how you should cite your references within the paper.

What is biology?

Biology is a branch of science that deals with living organisms and their vital processes. Biology encompasses diverse fields, including botany , conservation , ecology , evolution , genetics , marine biology , medicine , microbiology , molecular biology , physiology , and zoology .

As a field of science , biology helps us understand the living world and the ways its many species (including humans ) function, evolve, and interact. Advances in medicine , agriculture , biotechnology , and many other areas of biology have brought improvements in the quality of life. Fields such as genetics and evolution give insight into the past and can help shape the future, and research in ecology and conservation inform how we can protect this planet’s precious biodiversity .

Where do biology graduates work?

Biology graduates can hold a wide range of jobs, some of which may require additional education. A person with a degree in biology could work in agriculture , health care, biotechnology , education, environmental conservation, research, forensic science , policy, science communication, and many other areas.

biology , study of living things and their vital processes. The field deals with all the physicochemical aspects of life . The modern tendency toward cross-disciplinary research and the unification of scientific knowledge and investigation from different fields has resulted in significant overlap of the field of biology with other scientific disciplines . Modern principles of other fields— chemistry , medicine , and physics , for example—are integrated with those of biology in areas such as biochemistry , biomedicine, and biophysics .

Biology is subdivided into separate branches for convenience of study, though all the subdivisions are interrelated by basic principles. Thus, while it is custom to separate the study of plants ( botany ) from that of animals ( zoology ), and the study of the structure of organisms ( morphology ) from that of function ( physiology ), all living things share in common certain biological phenomena—for example, various means of reproduction , cell division , and the transmission of genetic material.

Biology is often approached on the basis of levels that deal with fundamental units of life. At the level of molecular biology , for example, life is regarded as a manifestation of chemical and energy transformations that occur among the many chemical constituents that compose an organism. As a result of the development of increasingly powerful and precise laboratory instruments and techniques, it is possible to understand and define with high precision and accuracy not only the ultimate physiochemical organization (ultrastructure) of the molecules in living matter but also the way living matter reproduces at the molecular level. Especially crucial to those advances was the rise of genomics in the late 20th and early 21st centuries.

Cell biology is the study of cells—the fundamental units of structure and function in living organisms. Cells were first observed in the 17th century, when the compound microscope was invented. Before that time, the individual organism was studied as a whole in a field known as organismic biology; that area of research remains an important component of the biological sciences. Population biology deals with groups or populations of organisms that inhabit a given area or region. Included at that level are studies of the roles that specific kinds of plants and animals play in the complex and self-perpetuating interrelationships that exist between the living and the nonliving world, as well as studies of the built-in controls that maintain those relationships naturally. Those broadly based levels— molecules , cells, whole organisms, and populations—may be further subdivided for study, giving rise to specializations such as morphology , taxonomy , biophysics, biochemistry, genetics , epigenetics , and ecology . A field of biology may be especially concerned with the investigation of one kind of living thing—for example, the study of birds in ornithology , the study of fishes in ichthyology , or the study of microorganisms in microbiology .

Basic concepts of biology

Biological principles.

The concept of homeostasis —that living things maintain a constant internal environment—was first suggested in the 19th century by French physiologist Claude Bernard , who stated that “all the vital mechanisms, varied as they are, have only one object: that of preserving constant the conditions of life.”

As originally conceived by Bernard, homeostasis applied to the struggle of a single organism to survive. The concept was later extended to include any biological system from the cell to the entire biosphere , all the areas of Earth inhabited by living things.

All living organisms, regardless of their uniqueness, have certain biological, chemical, and physical characteristics in common. All, for example, are composed of basic units known as cells and of the same chemical substances, which, when analyzed, exhibit noteworthy similarities, even in such disparate organisms as bacteria and humans . Furthermore, since the action of any organism is determined by the manner in which its cells interact and since all cells interact in much the same way, the basic functioning of all organisms is also similar.

There is not only unity of basic living substance and functioning but also unity of origin of all living things. According to a theory proposed in 1855 by German pathologist Rudolf Virchow , “all living cells arise from pre-existing living cells.” That theory appears to be true for all living things at the present time under existing environmental conditions. If, however, life originated on Earth more than once in the past, the fact that all organisms have a sameness of basic structure, composition , and function would seem to indicate that only one original type succeeded.

A common origin of life would explain why in humans or bacteria—and in all forms of life in between—the same chemical substance, deoxyribonucleic acid ( DNA ), in the form of genes accounts for the ability of all living matter to replicate itself exactly and to transmit genetic information from parent to offspring. Furthermore, the mechanisms for that transmittal follow a pattern that is the same in all organisms.

Whenever a change in a gene (a mutation ) occurs, there is a change of some kind in the organism that contains the gene. It is this universal phenomenon that gives rise to the differences ( variations ) in populations of organisms from which nature selects for survival those that are best able to cope with changing conditions in the environment .

Biology Extended Essay: The Complete Guide for IB Students

by  Antony W

March 13, 2023

Biology Extended Essay is an assignment that requires you to explore biological issue relevant to you and your environment.

Your focus should be on a particular biological emphasis within a broader context of scientific investigation. Given that the focus is on a biological system, you’ll have to make an analytical argument as you write the essay.

In this guide, you’ll learn exactly what you need to know about the IB Biology Extended Essay . Our goal with this lesson is to give you the most important information about the subject so that you can get the assignment done right.

What is Biology in an IB Extended Essay?

Biology in IB Extended Essay is the examination of living organisms and their life processes. The assignment integrates biological theories and examines the nature of the subject.

While you can approach a Biology EE from varying viewpoints, the treatment of the material used in your investigation must be 100% biological.

IB Biology Extended Essay Topics

The topic you choose to explore in your IB Biology Extended Essay shouldn’t be too broad or too narrow. Make sure you choose a focused topic that’s easy to investigate and easy to explain.

Your teacher expects you to explain how you arrived at your research question, and the best way to do that is to outline the aspects you wish to consider in the essay.

You may also have to formulate one or more hypothesis based on the research question.

The EE guide on the subject recommends that you choose your topics carefully, making sure you refrain from inappropriate topics such as those that are likely to inflict pain, involve the use of dangerous substances, or linked to safety concern.

You should avoid topics whose outcome are either obvious or already well known and documented in textbooks.

Doing Research for Your IB Biology Extended Essay

You will need to do primary and secondary research for your Biology Extended Essay.

1. Primary Research

For primary research, you can collect data from fieldwork, surveys, biological drawings, and biological observations.

If you’ve picked topic that requires practical work, you may have to conduct multiple, extensive fieldwork or do lab tests. In such a case, you will have to provide a detailed explanation of the experimental research procedures sued.

2. Secondary Research

When it comes to secondary research, you get data or information from literature.

Some students restate the information they collect from secondary sources, but doing so often adds little or no value to a Biology Extended Essay.

Therefore, the right approach is to analyze the data or information in an original way to add a new dimension and value to your research and to the essay at large.

Whether you do primary research, secondary research, or a combination of both, you need to make sure you have access to enough data or information to answer your research question.

How Do You Write an IB Biology Extended Essay?

The first step to writing a comprehensive, 4,000-word essay in Biology EE is to use the right scientific techniques to analyze the data you collect during research.

You then have to present your argument or evaluation based on the analysis you’ve completed.

You can include graphs, tables, and diagrams, and make sure you point out their significance in the essay so they’re easy to understand.

As with any other EE, your Biology essay should have a good structure and demonstrate a logical progression. Feel free to use headings and subheadings in the essay because it imposes a concise structure.

Your evaluation of the research questions should demonstrate that you not only understand the results from your experiments but also can explain their significance in a wider academic context.

Since you aren’t sure about what to expect from biological experiments, you may have to account for anomalies or unexpected results in your investigation.

In such a case, you have to provide explanations for the expected outcome and give an alternative explanation for such findings.

The subject also allows you to propose slight or major changes to the hypothesis presented in the essay, in which case you will have to suggest relevant approaches to testing the new changes.

Evaluation of Your Biology EE

Writing your EE in Biology also requires that you undertake a critical evaluation of the work that you have already done.

The evaluation helps you to identify and explain the limitation of your research by a number of factors including the reliability and validity of statistics, the precision of experimenting equipment and the reliability of sources.

You also need to consider biological limitations of your research. Such limitations are likely to arise from the inability to generalize based on a single form of an organism or problems of control and repeatability when using living organisms in your research.

Biology Internal Assessment vs Biology Extended Essay

It’s important to keep in mind that a Biology Extended Essay is not an extension of the Internal Assessment in the same subject. There are a few differences that set the two assignments apart, and it’s important to know them before you start working on the essay.

Areas of Research for Biology Essays

If you’ve been assigned to write a biology essay, you probably know which area of research you have to choose. However, it might be beneficial to explore other available scopes. It’s useful for both interdisciplinary study and the cases when you are free to pick your area of research. In this section, let’s figure out what you can study in biology.

Here are biological areas of research you should be familiar with:

• Cancer Biology studies this type of disease to prevent, detect, diagnose and cure it. The ultimate goal of such biologists is to eliminate cancer.
• Cell Biology is a branch that studies the structure, function, and behavior of cells. Here, biologists study healthy and sick cells to produce vaccines, medication, etc.
• Biochemistry is an application of chemistry to the study of biological processes on cell and molecular levels. It is a cross-discipline between chemistry and biology. The focus is on the chemical processes of living organisms.
• Computation Biology is a study of biological data that develops algorithms and models to understand biological systems. Here, scientists either work for institutions or research for private enterprises.
• Genetics is an area that focuses on the study of genes and genetic variations for health benefits. It looks at the way DNA affects certain diseases.
• Human Disease is an area within which scientists study different diseases. The field covers cancer, developmental disorders, disease genes, etc.
• Immunology is a branch of biology that focuses on immunity. Immunologists look at the way the body responds to viruses as a way to protect the organism.
• Microbiology studies all living organisms that are too small for our eye to see. It includes bacteria, viruses, fungi, and other microorganisms.
• Neurobiology is the study of the nervous system. Biologists examine the way the brain works and look into brain illnesses.
• Stem Cell and Developmental Biology seeks to examine how the processes behind stem cell’s ability transform cells. The biologists in this area use the power of stem cells to model human illnesses.

Essay on Biology: Writing Tips

Want to know how to start a biology essay? Wondering about the best way to write your essay on biology? Then check out the following tips.

When you’re writing about biology, pay attention to the following features:

• Introduction . Just as in any other form of academic writing, the first section of your paper introduces the subject. Here, explain why your ideas are relevant to biology as a science.
• Thesis Statement. The final one or two sentences of the first paragraph should include your original hypothesis and experiment. You will be proving them in the main body. You do not have to include the results as the reader will encounter them later. If you’re struggling with this part, try our thesis generator .
• Main Body. In this part, write about all the experiments in detail. Often, teachers require to include visual aid to prove your point. For Zoology, Anatomy, Botany, it is pretty easy to find some photos and illustrations.
• Conclusion. Here, restate your thesis. Reemphasize the most critical aspects described in the main body. You can do it by using our summarizing tool . The goal of this last paragraph is to leave an everlasting impression on the reader.
