crassulacean acid metabolism (CAM)

a method of PHOTOSYNTHESIS found in certain succulent plants (members of the family Crassulaceae) that live in hot, dry climates and close their stomata during the day to avoid excessive TRANSPIRATION losses and open them at night. During the night CO2 is taken in and stored as organic acids (e.g. malic acid); during the day the CO2 is released from the organic acids and used in the CALVIN CYCLE.
