Expert Answer:

  • Transpiration is the loss of water in the form of water vapour from the aerial parts of a plant.
  • It occurs through openings called stomata.
  • Water loss through evaporation lowers the concentration of water inside the mesophyll cells.
  • Due to this, water enters mesophyll cells from neighbouring xylem vessels through osmosis.
  • As water evaporates from the leaves, a suction force is created. This force helps to draw more water up through the stem which causes the roots to absorb more water from the soil.
  • Higher the rate of transpiration, greater the rate of absorption of water and solutes from the soil.
  • Transpiration also helps in maintaining the temperature of the plant body.
