Question

Why does Stomatal areas cells are called guard cells. Give reasons..??

Answer 1

Plants 'breathe' and 'sweat' through their stomata, which are regulated by guard cells. Guard cells have a very important job because by opening and closingstomata, they facilitate gas exchange for photosynthesis and help minimize water loss.

Answer 2

Guard cells are important for functioning of stomata .

Each stoma is guarded by a pair of bean shaped guard cells which govern the opening and closing of stomatal aperture.
That's why they are important.


Stomata :

Stomata in the epidermis of leaves help in gaseous exchange during respiration and photosynthesis.
