Question
CAM pathway helps plants to _______________.
- Reduce water loss
- Develop disease resistance
- Improve flowering
- Improve budding
Hint:
To minimise the water loss in these plants, e.g. cactus, stomata opens at night and carbon dioxide is stored in the vacuoles as malic acid.
The correct answer is: Reduce water loss
- CAM or Crassulacean acid metabolism helps in reducing loss of water by transpiration. To minimise the water loss in these plants, e.g. cactus, stomata opens at night and carbon dioxide is stored in the vacuoles as malic acid.
