Definitions:

CAM

A type of photosynthesis (Crassulacean Acid Metabolism) adapted by some plants to minimize water loss in arid conditions by fixing CO2 at night.

CAM Plants

Plants that utilize Crassulacean Acid Metabolism, a carbon fixation pathway that allows them to conserve water in arid conditions by opening their stomata at night.

Stomata

Microscopic openings on the surfaces of leaves and stems that regulate gas exchange and water vapor between the plant and the atmosphere.

Photosynthesis

The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water, producing oxygen as a byproduct.
