Like all eukaryotes, plants and algae undergo the same biochemical reaction that provides the ATP necessary for everyday functions that maintain their homeostatic lives: cellular respiration. One major difference between all eukaryotic organism and plants is the plant’s ability to produce their own food through the process of photosynthesis. While cellular respiration occurs in the mitochondria of all eukaryotes, plant’s photosynthesis occurs in the membrane bound chloroplasts, which are abundant inside the cell. Although both cellular respiration and photosynthesis share some similarities, it is important to note that photosynthesis, unlike cellular respiration, is an anabolic process.(Harris-Haller) This strenuous process works efficiently

The first part, the Light-Dependent Cycle, depends on the intake of water and light. These components are taken into the thylakoid membranes of the chloroplasts.(Campbell) More importantly, the solar energy provided by the intake of these components into the Photosystem II excites electrons in the chlorophyll causing them to jump to higher energy levels. The excited electrons are then bonded to primary acceptors and transported down the electron transport chain, in which ATP is created, to Photosystem I. (Campbell) The excitation of the electrons in Photosystem I allows for the electron binding of the primary acceptor and their transport through a second transport chain, which reduces NADP to NADPH. (Harris-Haller) These electron transport chains are crucial and provide the Calvin Cycle with the components it …show more content…
Before starting the experiment, it was hypothesized that white light would have the ultimate photosynthetic rate. While taking a look at Figure 1, it is clear that our hypothesis was correct. White light had the most amount of floating leaves and this is mostly due to the fact that white light covers the whole light spectrum. The graph also displays no photosynthetic rate for green light. This is due to the fact that green light is reflected not absorbed. The darkness also presented zero floating leaves and this is due to the fact that no light would mean that there was no energy source for photosynthesis to occur. The second highest was red and this is due to being a bigger wavelength than blue which also had some floating leaves. The reasoning behind the floating of the leaves is that there is a photosynthetic reaction occurring which produces oxygen in the deoxygenized leaves making them float. (Osterhoudt) The leaves under the white light experienced the most photosynthetic
