You perform an experiment using an aquatic plant to determine which color of light is most effective at driving photosynthesis. You take three plants, immersed under water, place plant A under blue light, plant B under red light, and plant C under green light. You notice bubbles coming off the leaves. More bubbles are coming from plants A and B, than plant C. How do these results determine which color of light is most effective at driving photosynthesis
