Transpiration in plants

Why plants become wilt?

• Less water evaporate from the plants

• The plant loss excessive amount of water through transpiration

• The stomata of the plants are closed

• The weather are cool.

What do you understand about guttation?

• The water loss from plants in liquid form through stoma on the surface of the leaves.

• The water loss from plants in liquid form through hydathodes(opening) at the edge of the leaves.

• The water loss from plants in the form of water vapour through hydathodes(opening) at the edge of the leaves.
