Question

Definition of stomatal transpiration

Answer 1

Answer:

It is the loss of water through specialized pores in the leaves.

Answer 2

Answer:

• Loss of water through stomata is called stomatal transpiration.

• Stomatal transpiration takes place when the stomata are open (i.e. generally in day time) and the process stops when the stomata get closed (i.e. generally in night).

• Opening and closing of stomata occurs due to osmotic changes in guard cells.

• When the guard cells are turgid (due to endosmosis), the stomata get opened.

• When guard cells become flaccid (due to exosmosis), the stomata get closed.
