Question

Give reason respiration is a continuous process and does not depend on opening and closing of stomata

Answer 1

Yes respiration is a continuous process and does depend on opening and closing of stomato because during the respiration stomato become not up down we take breathe impossible

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.
