- Transpiration is the loss of water in the form of water vapour by evaporation from surface of plants into the atmosphere.
- (4) The evaporation of water from the mesophyll cells removes heat from the leaves. This produces a cooling effect to plants.
- (3) Transpiration helps the supply of water for photosynthesis and to maintain turgid plant cells.
- (2) Transpiration creates suction pull for the transport of water and ions in the xylem vessels.
- (1) Transpiration pull helps the absorption of water by the roots.
- The Environmental Factors that Affect Rate of Transpiration
1. The rate of transpiration can be affected by the following environmental factors:
(a) Light intensity
(b) Temperature
(c) Air movement
(d) Humidity
