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, COconverts to glucose by Calvin cycle.
