Biology research paper structure

Now that you have chosen your biology topic, it’s time to turn it into reality.

All of the information you choose should find its proper place in your biology research paper.

And to make your paper easy to read and effective, you should keep in mind the primary principles of structuring a research paper.

So, let’s find out what elements you need to present in your biology project.

A research structure is similar to the shape of an hourglass, and your biology project structure is no different. To make such a framework, complete the following steps:

  1. Find a broad field of biology.
  2. State the general biology questions within that sphere.
  3. Narrow these topics to one biology subject.
  4. Do thorough research and investigation into that subject.
  5. Describe biology experiments and theories related to the topic.
  6. Analyze the results and draw conclusions.
  7. Generalize from your results to broader biology questions.


To organize all of these principles effectively, follow the typical structure of a literature review by dividing your biology research paper into the following paragraphs.

  1. Abstract

This is a short section that summarizes your research. Express the most important ideas of your work, and then include the results of your biology experiments.

Although this may sound strange, it’s better to write your abstract at the end of your work. It’s difficult to draw all the conclusions and succinctly explain your paper when it isn’t complete yet.

  1. Introduction

An introduction to a biology topic doesn’t differ much from a standard essay introduction. Here you should reveal the major biology questions. Highlight those that are discussed in your chosen field, and then give a general scene of your topic.

This is also the time to talk about your research weaknesses. What theories seem disputed? Which biology experiments are difficult to complete? What ideas cannot be proved? You can answer these questions or choose your own based on your topic.

  1. Methods

The methods section explains how you performed your research. You can’t write about the results of your work without describing the tools that helped you.

The methods paragraph makes your biology research repeatable and thus confirmable. It also helps other scientists evaluate your scientific approach.

  1. Results

This section of your biology project is vital because it contains an analysis of your work. You should provide all of your results in this section, even if your biology research paper gives a lot of information.

Explain your findings and support them with figures and facts.

  1. Discussion

In the discussion section, criticize your work. It’s important to be honest. Share the disadvantages of your biology research with other scientists so they can understand your experiment and possibly improve it.

This step also helps other researchers avoid your mistakes by following your advice.

  1. Conclusion

The conclusion paragraph is where you can discuss general biology questions. Mention how your biology experiments can help scientists solve those problems.

Try to include the most important ideas about how to solve different but related issues.

  1. References

Don’t forget to provide all necessary details about the work that helped you do your research.

And that’s it! This is the structure of a biology paper. Keep these tips in mind while doing your research and composing your paper.

Now you’re ready to write an awesome paper on any important biology topic yourself!
