Question

Give an account of stomatal transpiration.​

Answer 1

Answer:

Stomatal transpiration:

• 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.

Answer 2

Answer:

Stomatal transpiration is the evaporation of water from a plant's stomata. ... Near the surface of the leaf, water in liquid form changes to water vapor and evaporates from the plant through open stomata.
