  • Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.

Transpiration measured by potometer.Potometer actually measure water suction result of transpiration.

Type of potometre

  • Ganongs
  • Farmer's

Type of transpiration

  • Stomatal
  • Cuticular
  • Lenticular

Advantage

  • Help in salt absorption.
  • Help in ascent of sap.
  • Regulate plant temperature.

Disadvantages

Transpiration have more disadvantages than advantages

  • Cause water scarcity.
  • Result in water deficit in plant.
