Effects of Light on Chloroplast and Oxygen Production in Anacharis

The purpose of our research project was to determine how light affects the use of oxygen by chloroplast, and how light affects the plant's production of chloroplast. We used a dissolved oxygen meter to test the amount of dissolved oxygen in tanks containing the same amount of plant life, but receiving either constant light, or constant darkness. We used a photospectrometer to determine the amount of chlorophyll present in the plants. We found that plants use oxygen when placed in the dark, and give off oxygen when placed in the light. Chloroplast also grows best in light.
