Question

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

Answer 1

Heya!!Here is your answer friend ⤵⤵

⏪STOMATA : the tiny pores present on the surface of the leaves for gaseous exchange are called stomata.

➡Guard cells regulate the opening of stomata.

➡When excessive water flows in through the pores , the guard cells swell up causing the stomatal to open .

➡When less water flows in the pores , the guard cells shrink causing the pores to close .



Hope it helps you ✌✌

Answer 2

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. Simillarly the pore closes if the guard cells shrink
