Question

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

Answer 1

Answer:

The opening and closing of the pore is a function of the guard cells. The guard cells swell when water flows into them, causing the stomatal pore to open. Similarly the pore closes if the guard cells shrink.

Answer 2

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.
