(1)Transpirational pull created by transpiration of water from leaf surface causes ascent of sap (upward movement of water and mineral salts).
(2)The sap absorbed from the soil contains low concentration of mineral salts.
(3)The loss of water through transpiration increases the concentration of mineral salts in the plant.
(4) Due to the heat of the Sun, temperature of the plant increases which may be harmful for the plants.
(5)Excess dehydration reduces the rate of photosynthesis and other metabolic activities, which may further lead to deformation in plants.
(6)Transpiration lowers down the temperature of the plant by 10°-15°C.
(7)Due to transpiration being higher than the rate of water absorption at noon time wilting or loss of turgidity is quite common.
