(CAM plant)

CAM stands for Crassulacean Acid Metabolis. At night CO2 enters the stomata and it is converted into a four carbon organic acid which releases CO2 for the Calvin Cycle of Photosynthesis during the day, when the stomata are closed. When the stomata are closed it helps prevent excessive water loss.CAM is an adaptation to conditions too hot and dry to support vegetation. CAM plants often have thick, reduced leaves and a low surface-area to volume ratio.They also have thick cuticles.Pineapples (above) and cacti are examples of CAM plants.
