Question

How do the guard cell regulate opening and closing of stomatal pores

Answer 1

Guard cells regulate the opening and closing of the stomata and this regulation is brought about by the movement of water in and out of the guard cells. When water moves into the guard cells, they become flaccid. This causes the outer walls of cells bulge out and vice-versa.

Answer:

Stomatal pores in plants regulate the amount of water and solutes within them by opening and closing theirguard cells using osmotic pressure. In order for plants to produce energy and maintain cellular function, their cellsundergo the highly intricate process of photosynthesis. Critical in this process is the stoma.
