what is transpiration list its two functions
Transpiration is the process by which plants lose excess water in the form of water vapour through tiny pores called stomata present mainly on the leaves.
It is a natural process that occurs continuously in plants, especially during daytime.
Two functions of transpiration
Helps in absorption and movement of water
Transpiration creates a pulling force called transpiration pull, which helps roots absorb water and minerals from the soil and transport them to different parts of the plant.
Maintains temperature of the plant
Evaporation of water cools the plant and protects it from overheating, similar to sweating in humans.
Importance of transpiration
Helps in mineral transport
Removes excess water
Maintains water balance in plants
Thus, transpiration is essential for the proper growth and survival of plants.
