CAM plants

                                                    14. CAM plants

 CAM plants are plants that grow in an arid evironment. They use a carbon fixation pathway that allows them to cloase their stomata during the hottest part of the day to prevent water loss. Instead their stomata are open at night to allow for the storage of CO2. Then during the day the CO2 is released to be used in the calvin cycle. This cactus represents a CAM plant because they are normally found in dry and arid environments.
