CAM plants (e.g., succulents) reduce water loss by
- A
Eliminating chlorophyll in mesophyll
- Bcheck_circle
Opening stomata only at night to fix CO₂
- C
Doing aerobic respiration in daylight
- D
Carrying out photosynthesis underwater
Explanation
CAM = Crassulacean Acid Metabolism. Stomata open at night (cool, humid), fixing CO₂ as malate; daytime closed stomata limit transpiration while malate releases CO₂ for the Calvin cycle.
