Question

Why do CAM plants close their stomata during the day?

Answer 1

CAM plants keep their stomata closed during the day for the following reasons:

1. CAM plants usually close their stomata during the day and open them at night.
2. When the stomata are closed, water loss is prevented by the process of evaporation.
3. This process prevents carbon dioxide gas from entering the plant's leaves.
4. Carbon dioxide gas accumulates during the night and is stored in plants in the form of organic acids until the day begins.
5. These plants have different strategies that prevent them from storing water.
