what is transpiration list its two functions

Verified Answer

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

  1. 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.

  2. 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.
