What will be the effect of accumulation of `K^(+)` ions in guard cells

A

Water potential increases

B

Water potential decreases

C

Loss of turgidity

D

Exosmosis

Text Solution

Verified by Experts

The correct Answer is:
B
Accumulation of `K^(+)` results increase in the osmotic potential of guard cells and consequently its water potential is decreased. This results in the movement of water into the guard cell from surrounding cells. The guard cells become turgid and swell. Thus the stomatal pore becomes open.
