Question

What is stomatal transpiration ?
Explain ?​

Answer 1

Answer:

Stomatal transpiration is the process through which water is lost through the stomata. This water loss accounts for roughly 80%-90% of the water lost from the plant. This process allows the plant to continually draw more water up through the roots, even in regions (such as mangroves) where the osmotic pressure would normally draw water out of the plant

Explanation:

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.
