- You are a marine biologist sampling an offshore ecosystem. One day, you find a red organism floating in one of your nets. It has structures that resemble the leaves and stems of a plant. You hypothesize that this organism might be photosynthetic. Describe how you could test this hypothesis using a pH indicator solution. a. In detail, describe the steps you would take and the reactants of photosynthesis required. b. What change in pH would indicate that the organism was undergoing photosynthesis, and how would the indicator respond?arrow_forwardWhich of the following options best explains how less chlorophyll would affect the proces of photosynthesis in plants? 6. A. It would increase the rate of photosynthesis because of the increased production of food. B. It would limit the amount water plants are able to take in, resulting in a slower rate of photosynthesis. C. It would increase the production of oxygen because the plant would need to work hard to feed themselves. С. D. It would limit the amount of light absorbed by the plant and decrease the amount of food the plant is able to produce for itself.arrow_forwardWhat do photosynthesis and cellular respiration have in common?
