Transpiration is the loss of water from a plant in the form of water vapour. Water is absorbed by roots from the soil and transported as a liquid to the leaves via xylem. In the leaves, small pores allow water to escape as a vapour. Of all the water absorbed by plants, less than 5% remains in the plant for growth. Transpiration decreases the hydrostatic pressure in the upper parts of the plant creating transpiration pull due to which water easily move against gravity from roots to upper parts. Water absorbed in the root moves upward due to this transpiration pull and capillary action.
