Plants that carry out crassulacean acid metabolism (CAM) differ from C₄plants in that

Question

Quizplus · Accepted Answer

Plants that carry out CAM open their stomates at night to take in CO2, which they store as malic acid. During the day, the stomates are closed to prevent water loss and the stored malic acid is broken down, releasing CO2 for photosynthesis. This is different from other plants that have stomates open during the day, such as C3 and C4 plants. The other choices are incorrect, as CAM plants do contain PEP carboxylase and do carry out the Calvin cycle, although these processes occur at different times than in other plants. CAM plants still need ATP for photosynthesis, and they do contain rubisco, although its activity may be reduced compared to C3 and C4 plants.
