Question

20. How is closing and opening of stomata cause​

Answer 1

Explanation:

The root pressure which conducts low and high pressure . Along this water requirement also change so this root pressure allows the stomata pore to open is same as transpiration. So the guard cells swells up help in open the stomata pore.

When there is high pressure of water in leaves the guard cells are shrink as the stomata pore to close.

Answer 2

Answer:

as the stomata opens the solute concentration reduces, this makes water from the guard cell to move away into the neighbouring cells.

if the guard cells become flaccid with no water they collapse with each other resulting to closing of the stomata
