CAM plants A) do not perform any part of photosynthesis during the day. B) fix CO₂ in mesophyll cells during the day. C) include economically important food crops like corn and sugarcane. D) open their stomata at night to minimize water loss. E) typically grow very quickly because they are found in hot, moist environments.

Question

Quizplus · Accepted Answer

CAM plants (Crassulacean Acid Metabolism) open their stomata at night when it is cooler and more humid to take in carbon dioxide. They store this carbon dioxide as an intermediate molecule and then use it during the day to perform photosynthesis without opening their stomata, reducing water loss in hot and arid environments.
