CAM Photosynthesis

Crassulacean acid metabolism (CAM), a type of nocturnal/diurnal photosynthesis that occurs in succulents and that is useful in carbon isotope analysis. CAM plants are found in arid regions and are at low risk of losing carbon through photorespiration. Less than 3-4% of the earth’s plant species can be characterized as CAM plants.

Cf. C4 photosynthetic pathway.
