Heyya!
Definition:- the evaporation of water or loss of water in vapour form, from the exposed parts of a plant especially leaves is termed as transpiration.
Advantages of Transpiration:-
(1) Ascent of sap:Transpiration developes tension in the water column which makes it possible for the water to rise from the xylem of the roots to the top of the plant.
(2) Removal of excess water : Plants absorb far more water than is actully required by the plants.Transpiration helps in removing this excess water.
(3) Absorption & distribution of salts: The rate of salt absorption increases with the rate of transpiration.
(4) Cooling effect:- Sunlight that falls on the leaf can raises the leaf temprature by 30-40 degree centigrade above the atmospheric temperature,and thus harm the leaf tissues.A major portion of this energy is dissipated by transpiration when the water evaporates leading to a cooling effect..
(5) Development of root system: Transpiration allows extensive development of the root system that supports the heavy aerial growth against storms & allows absorption of mineral salts & water.
Hope it helps!☺️

Transpiration is the process by which water is released out of the leaves of the plants. These leaves hav chlorophyll in them which possess extra water. Therefore, this removal of extra water occurs only in green (chlorophyll containing) plants.
