The stomata ____.

Question

The stomata ____.

Quizplus · Accepted Answer

Stomata are open when the guard cells are swollen with water. The opening and closing of stomata is controlled by the turgor pressure within the guard cells. When water enters the guard cells, they swell and the stomata open, allowing for gas exchange and transpiration. When water moves out of the guard cells, they become flaccid and the stomata close to conserve water.

Note: Option A is incorrect as stomata are open during the day in most plants. Option C is incorrect as stomata close when water moves out of the guard cells. Option D is incorrect as the cuticle covers the epidermis of the leaf, not the stomata. Option E is incorrect as stomata do not allow water to enter plant leaves, instead they allow gases to enter and leave.
