CAM Plants

CAM plants also have a mechanism for dealing with photorespiration.
  • Stomata open at night: CO2 enters, is fixed by PEP carboxylase and converted to malate.
  • Malate is stored in vacuoles until daytime.
  • Stomata close during the day: malate is broken down into CO2 which enters the Calvin cycle.


Examples of CAM Plants

Pineapple, cacti, succulents.
