उत्तर
Plants absorb more water than what is required. Out of 100%, only 5% of the water is used in metabolic reactions while the remaining 95% is released into the atmosphere as transpiration.

(i) It helps in transportation of water and minerals to the various parts of the plant.
(ii) It produces a cooling effect to the plants.
(iii) It evaporates excess water.
