  2. High temperature of air.
  3. High speed of wind.
  4. High light intensity.

  1. It helps to keep the plant cool in hot weather.
  2. Transpiration plays an important role in water cycle. It releases 10% of water back into the environment.
  3. It creates water vapour that forms into fog and cloud.
