Answer 2

There are two theories about the opening and closing of stomata:

• Potassium ion concentration theory
• Sugar concentration theory

Potassium ion concentration theory:

This is the recent theory in which ATP is used to actively pump the potassium ions of the adjacent cells into the guard cells.

Sugar concentration theory:

This the old theory in which the guard cells become turgid and bulbs out words due to their thin outer wall, thus widening the stomatal opening lying in between.
