Question

How is opening and closing of
stomatal pores regulated in leaves?
​

Answer 1

Explanation:

The opening and closing of stomata are controlled by the guard cells. When water flows into the guard cells, they swell up and the curved surface causes the stomata to open. When the guard cells lose water, they shrink and become flaccid and straight thus closing the stomata.

Answer 2

closing and opening of stomata is regulated by the functions of guard cells.

• When there's more water in guard cells it swell up resulting in opening of stomata.

• When there's less water in guard cells it shrinks resulting in closing of guard cells.
