Write short notes on:Transpiration

Answer»
  • Plants give out water in the form of water vapour through the stomata on their leaves. This is known as transpiration. 
  • Two cells called guard cells are present around the stomata. They control the opening and closing of stomata. 
  • Water is released into the atmosphere by leaves through the process of evaporation.
  • As a result, water in the epidermal layer of the leaf decreases. 
  • Water is brought up to the leaves through the xylem to compensate for the lost water. 
  • Transpiration helps in absorption of water and minerals and distribution to all parts of the plant.
