How does this minimize water loss by such plants? How does this minimize water loss by such plants?
A. CAM plants are able to fix CO2 and accumulate carbon in the form of organic acids during the night, when the loss of water through open stomata thereby is minimized. During the day, when solar energy is available but the potential for water loss is highest, CAM plants close their stomata and channel carbon from malate into the Calvin cycle.
B. CAM plants are able to fix CO2 and accumulate carbon in the form of organic acids during the night, when the loss of water through closed stomata thereby is minimized. During the day, when solar energy is available, CAM plants open their stomata and channel carbon from malate into the Calvin cycle.
C. CAM plants are able to fix CO2 and accumulate carbon in the form of organic acids during the day, when solar energy is available and when the loss of water through open stomata is minimized. During the night, when the potential for water loss is highest, CAM plants close their stomata and channel carbon from malate into the Calvin cycle.
D. CAM plants are able to fix CO2 and accumulate carbon in the form of organic acids during the day, when solar energy is available and when the loss of water through closed stomata is minimized. During the night, when the potential for water loss is highest, CAM plants open their stomata and channel carbon from malate into the Calvin cycle.

Answer:
A. CAM plants are able to fix CO2 and accumulate carbon in the form of organic acids during the night, when the loss of water through open stomata thereby is minimized. During the day, when solar energy is available but the potential for water loss is highest, CAM plants close their stomata and channel carbon from malate into the Calvin cycle.
Reason:
Crassulacean acid metabolism (CAM): The major problem with these metabolic plants in which lot of water loss may occur, to avoid this, CAM plants usually open stomata during nights and mainly closed during the day further A. CAM plants are able to fix CO2 and accumulate carbon in the form of organic acids during the night, when the loss of water through open stomata thereby is minimized. During the day, when solar energy is available but the potential for water loss is highest, CAM plants close their stomata and channel carbon from malate into the Calvin cycle.

Desert plants absorb CO2 at night (stomata are closed during the day to prevent water from leaving the plant). CO2 is converted into malate, which is stored in vacuoles until morning. Why would plants not be able to directly store CO2 inside of vacuoles?
