Jenny thinks that photosynthesis occurs fastest in high light intensities. She designed an experiment to prove this. She got 3 plants and placed each in a different light intensity, one in low, one in medium, and one in high. Each plant received the same amount of water each day. After 3 weeks, she measured the rate of photosynthesis in each plant.
How did Jenny measure the rate of photosynthesis?
