CAM PLANTS AND CAM PHOTOSYNTHESIS
CAM plants (Crassulacean Acid Metabolism):
→CAM plants are adapted to live in hot and arid regions.
→These plants, open their stoma during the night and close it during the day.
→Thus, they could take CO2 from the atmosphere and also, conserve their water.
Examples: Golden root, Pineapple, Cactuses, Bromeliads...
*The Photosynthesis of CAM Plants:
During the night:
→The plant opens its stoma and thus, CO2 enters into the cell.
→Then, PEP carboxylase adds CO2 to PEP and produces oxaloacetate.
→After that, The oxaloacetate converts to malate.
→Finally, the malate stores within the vacuoles.
During the day:
→The plant closes its stoma and then, the malate enters into the cytoplasm.
→After that, the malate is broken down into CO2 and pyruvate.
→Finally, CO2 converts to glucose by Calvin cycle.
