Photosynthesis essay poses a great challenge to many students who are specializing in biology. Indeed, the process by which plants make their food is a bit difficult to understand and most people see it as abstract. To shed more light, many people are only conversant with the physical process, in which the actions are visible and tangible. In addition, photosynthesis essay dwells in the process in terms of its input and the outcome. For one to have a better knowledge of photosynthesis, the experimental part of the essay has to be carried out. For example, two plants have to be put under different experimental controls and left for a considerable number of days. At the expiry of the time allocated, the two plants are then observed and examined for both physical and chemical changes.

In fact, the differences found on the two plants would then be used to help the writer to present a convincing photosynthesis essay. Other than the experiment, there are several literatures that have been presented on photosynthesis. Therefore, one can just do a thorough literature review on the topic and gather enough information that could help him write a comprehensive essay on the topic. Apparently, the widely used method of collecting information is the internet due to accessibility and vast scholarly articles in photosynthesis as a topic.

In addition reading photosynthesis essay helps a student to gain the confidence in explaining the biological process. The explanation may be in a scholarly manner, thus from a general perspective to a more specific one, thereby enabling a detailed information. It should be noted that writing in general omit other important areas that have to be discussed.

Photosynthesis essay example

Plants, algae and many species of bacteria create their own food. All organisms that create their own food are called photoautotroph, or photosynthetic organisms. This is possible by a process called photosynthesis. This process converts carbon dioxide or CO2 into organic compounds using sunlight’s energy (Asimov, 1968).

Photosynthesis is a chemical process. It happens differently in different photosynthetic organisms. For instance, in plants, algae, and cyan bacteria, this process requires water, and carbon dioxide which are converted into organic compounds where oxygen, or O2 is released as a waste product. Now, this chemical process begins when proteins called photosynthetic reaction centers which contain chlorophylls, within photosynthetic organisms absorbs sun’s energy. In plants, these proteins are present inside chloroplasts, whereas in bacteria, they are present in the plasma membrane. The energy absorbed by chlorophylls is stored in form of adenosine triphosphate (ATP), and the rest of the energy is used in removing electrons that may exist in substance like water, which are then used in the reactions that converts carbon dioxide into organic compounds such as sugars (Asimov, 1968).

Photosynthesis plays a very important role as far as photosynthetic organism life is concerned. It maintains normal level of oxygen in the atmosphere because it releases oxygen as a waste product to the atmosphere. It is evident that nearly all life on earth depends on oxygen directly or indirectly. Organisms depend on oxygen directly as a source of energy or indirectly as a source of energy in the food they consume (Asimov, 1968).

For survival, photosynthetic organisms must make their own food. Carbon dioxide, water and energy from the sun are essential for this process to be completed (Asimov, 1968).
