Question
In a CAM plant, the concentration of organic acid
increases during the day
decreases or increases during the day
increases during night
decreases during any time
Solution
C.
increases during night
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 a plant using full CAM, the stomata in the leaves remain shut during the day to reduce evapotranspiration, but open at night to collect carbon dioxide (CO2).
