➪These are the functions performed by guard cells:

Guard cells are a pair of two cells that surround each stoma opening.

⇒They open and close the stomatal pore .

⇒They swell when water flows into them, causing the stomatal pore to open .

⇒Similarly the pore closes if the guard cells shrink.

⇒They protect the stomatal pore.

⇒They help to regulate transpiration.

⇒(In desert plants the stomata mostly remains closed in daytime when they have obtained the required CO2).
