Question:

Why is transpiration important for plants?

Answer:

Uptake of water and minerals from the roots to the leaves in the xylem is known as transpiration. It is important for the following reasons:-

  1. To carry forward the transpiration pull:- Cohesion- tension theory also known as transpiration pull. This theory includes high tensile strength and high capillarity; includes pull from soil to leaves.
  2. Transpiration pull to facilitate ascent of sap:- When the water moves upward to a tall tree, at the top of the tree develops a large tension, i.e, negative hydrostatic pressure is developed which pulls the water and the minerals through the xylem. This upward movement of the water and minerals against the gravitational force from roots to the aerial parts through xylem is known as the ascent of sap.
  3. Transpiration process helps to carry forward the photosynthesis process.
  4. It helps to get rid of the excessive water from the evaporation from the leaves.
