Photosynthesis In Plants - Essay Example Three leaves of the bouquet were covered by aluminum foil ensuring that the foil was blocking light from the leaves. The foil was removed from one leaf every week, photographed and observed for the three-week period.ResultsIn Figure 1, the leaves were green and healthy. Figure 2 shows leaves that had turned to light green and almost white in color. Vascular bundles were clearly visible in addition to the green spots on the leaf. The color at the center of the leaf was lighter than the periphery. Figure 3 shows leaves that are brown and dried out.DiscussionThe findings indicate that light is necessary for photosynthesis. The leaf in Figure 1 was green and healthy despite being covered by the aluminum foil because the energy in the chloroplast could still sustain photosynthesis. The leaf in Figure 2, was turning light green to indicate minimum photosynthesis was taking place. The leaf in Figure 3 had been covered for a longer period of time and the energy needed for photosynthesis was depleted. Moreover, there was no more light energy that could be absorbed for photosynthesis. This experiment shows that a low light intensity leads to a low rate of photosynthesis. This would deduce that an increased light intensity would lead to a high rate of photosynthesis at an optimum level.ConclusionIn summary, photosynthesis is essential for plants. Therefore water, temperature, light intensity and carbon dioxide should be made available to ensure the survival of plants.
