‎Transpiration is a necessary evil in plants because it is inevitable but potentially harmful. Loss of water from the plant results wilting and cause the death of a plant if a condition of drought is experienced. But transpiration is a great significance for the plant.

• Water is conducted, in most tall plants due to transpiration pull.
• Minerals dissolved in water are distributed throughout the plant body by Transpiration Stream.
• Evaporation of water from the cells of leaves has a cooling effect on plants.
• The wet surface of leaf cells allows gaseous exchange.
• Transpiration plays an important role in controlling the temperature of the plants.

${\sf{Transpiration\:: }}$

• Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.
• Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism.
• The remaining 97–99.5% is lost by transpiration and guttation.
