What will be an ideal response?
You perform an experiment using an aquatic plant called elodea to determine which color of light is most effective at driving photosynthesis. You take three plants, immersed under water, and 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, and few are coming from plant C. What is producing the bubbles? How do these results determine which color of light is most effective at driving photosynthesis? What will be an ideal response?
