Detailed explanation-1: -Sedum, Kalanchoe, Pineapple, Opuntia, Snake plant are the examples of CAM plants. These plants also perform double carbon dioxide fixation. The carbon dioxide acceptor in CAM plants is Phosphoenol pyruvic acid (PEP) during the night and Ribulose bisphosphate is carbon dioxide acceptor during the daytime.

Detailed explanation-2: -Some plants that are adapted to dry environments, such as cacti and pineapples, use the crassulacean acid metabolism (CAM) pathway to minimize photorespiration. This name comes from the family of plants, the Crassulaceae, in which scientists first discovered the pathway.

Detailed explanation-3: -Examples of CAM plants include orchids, cactus, jade plant, etc. Compare: C3 plant, C4 plant. See also: Crassulacean acid metabolism, Calvin cycle.

Detailed explanation-4: -Opuntia species are constitutive Crassulacean acid metabolism (CAM) plants, in which the capacity to induce CAM metabolism is developmentally regulated, with a progression from C3 to CAM metabolism occurring during cladode development.
