Biological Extended Essay Topics - Examples of Biology Extended Essay TopicsExtended essay topics often draw on biological concepts and ideas. But a biology graduate student may not have the knowledge or background to write an essay on the topic effectively. To help, here are some examples of biological, extended essay topics.The most basic example of a biological extended essay is one that asks students to discuss the origin of life. How did the first cells develop? How did the first animal, plant, or fungus reproduce? Where do we stand in the history of life?Since many people may be unfamiliar with some of the biological issues involved, the question of how did the first cells come to be is an excellent place to start. One idea is that life on earth began as photosynthesizing bacteria. Bacteria contain chlorophyll, which is a light-absorbing molecule. (We know that chlorophyll is absent from meteorites, but it is present in living things.)If the molecules that make up the early ear th were indeed formed by photosynthesizing bacteria, they would be composed of chloroplast proteins, which consist of polypeptide chains joined together in a ring. Photosynthesis is a process where plants produce oxygen from carbon dioxide through the oxidation of chlorophyll.The process of photosynthesis and the bacteria that carry out it allow the production of organic compounds, such as carbohydrates, and oxygen, which are a very important byproduct of the process. The molecules produced by photosynthesis include the building blocks of DNA, RNA, and amino acids. The first cells were not microscopic, but were rather large enough to be seen by the naked eye.For biology graduate students, one of the most interesting and difficult topics for extended essays to address is the problem of how the very first cells managed to split into two or more entities after the initial emergence. In fact, there has been much debate over the issue of the origin of life, particularly in the last centu ry.Biology graduate students are also given a challenge when they are asked to consider the importance of life to the natural world. This involves looking at the details of how different species are related to one another, the size of the ecological systems that support them, and how they are affected by the fluctuations in atmospheric pressure. These considerations are necessary to fully understand how we fit into the world.To help students master these topics, there are many excellent resources available to them. They can study them online and even take biology courses on campus.
