However, transpiration is beneficial to the plants in several ways.
1) Mineral Absorption: Minerals absorbed in water are absorbed into the roots; move up through the plant in the transpiration stream.
2) Optimum Turgidity: In some plants if transpiration is not allowed to occur, plants become very turgid, do not grow well and there is shortage of water in their cells.
3) Energy Exchange: When water is evaporated from the exposed surface of cells of leaves, it exerts a cooling effect on plant.
4) Effect on Growth and Development: Transpiration is a necessary factor in the normal growth of some plants e.g. pear, sunflower.
5) Absorption of Water: Water is conducted or transported in upward direction in most tall plants due to transpiration.
6) Exchange of Gases: Wet surface of leaf cells allow gaseous exchange.
