What is meant by CAM photosynthesis

Asked by Prajyot Tugaonkar | 4th Jun, 2013, 11:44: AM

Expert Answer:

Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions. In such plants, the stomata in the leaves remain shut during the day to reduce evapotranspiration, but open at night to collect carbon dioxide (CO2). The CO2 is stored as the four-carbon acid malate, and then used during photosynthesis during the day.
