In cacti, CO₂ is fixed during the night in a four-carbon molecule and stored in _______ for use in the Calvin cycle during the day. A) the stems, roots, and leaves B) the vacuoles of mesophyll cells C) sugar molecules D) the stroma E) the thylakoid lumen

Question

Quizplus · Accepted Answer

CO₂, also known as malate, is stored in the vacuoles of mesophyll cells during the night in CAM plants. It is then used in the Calvin cycle during the day when the stomata are closed to limit water loss. The other options are not correct as they do not involve the specific storage of malate in CAM plants.
