The Results of Densities in Brassica Rapa

Brassica Rapa is a a type of flower that comes from the mustard family. It is grown through the United States and Canada. Now High density , Low-density. In either case, photosynthesis will be key. Photosynthesis is “The process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and water using light as an energy source. Most forms of photosynthesis release oxygen as a byproduct” . The main job of photosynthesis is to convert CO2, H20, and light into sugar, or food, and oxygen. Now, to create these products, two processes have to occur: light reactions and the Calvin cycle. Light reactions occur in the thylakoid, C4 plants and C3 plants also exist.

For the experiment, a Biology class was gathered at Oakland University for the summer term of 2012. In the first week, the students were instructed to go to an adjacent room to take seeds that were labeled as Brassica Rapa and place them in two different containers in which soil was provided. Once the seeds were placed, they would be kept underneath a fluorescent light for 24 hours. The progress of the plants would be shown on a weekly basis. Moreover, as time went on, it could be easily seen that the growth was shown in both containers. The hypothesis is that the container containing the low density plants will grow faster than the high-density plants Results

The results that were gathered were quite remarkable, but several flaws could have intervened with them. For instance, one of the students that watered the plants could have over-poured or under-poured water for the plant and as a result, it could slow down its development. Moreover, the plants that were provided were genetically engineered by a professor at Oakland University. Therefore, the results that were gathered could not be related to normal Brassica Rapa plants. Now, although the genetic...
