Definition

Glossary of "Ecology (6th ed.)" by Krebs (2009)

• a form of photosynthesis in which the two chemical parts of photosynthesis are separated in time because CO₂ is taken up at night through the stomata (which are then closed during the day) and fixed to be used later in the day to complete photosynthesis carbon fixation; an adaptation used by desert plants to conserve water.

Glossary of "Evolution of Plants (2nd ed.)" by Willis & McElwain (2014)

• Plants that have a variation of the C4 pathway where crassulacean acid metabolism is used to fix atmospheric CO₂. Characteristic of most succulent plants.

Glossary of "Plant Biology (1st ed.)" by Graham et al. (2003)

• The metabolic pathway in which carbon dioxide is fixed at night by the C₄ pathway and simple sugars produced in the day by the C₃ pathway. The name derives from the stonecrop family of flowering plants (Crassulaceae) where this pathway was first recognized.
