Question

How do the guard cells regulate opening and closing of stomatal pores?

Answer 1

The introduction of water into guard cells aids in the opening of guard cells. The guard cell becomes turgid as a result of this. Water leaking from guard cells aids in the closing of guard cells. The guard cells will become flaccid as a result of this.

When water is introduced into guard cells, the cell becomes turgid, allowing the stomata to open. When water escapes from guard cells, the cell becomes flaccid, which causes the stomata to close.
