Solution

Evaporation:
Evaporation is a physical process where water is lost as water vapor.
Transpiration:
Transpiration is a physiological process where water is lost as water vapor.
Evaporation Transpiration
1 Evaporation is a physical process. 1 Transpiration is a physiological process.
2. It is controlled exclusively by external factors. 2. It is controlled by both external and internal factors.
3. It is a very fast process. 3. It is a slow process.
4. Light has no influence on evaporation. 4. Light controls transpiration as stomata open in presence of light and also contributes to the heating effect which in turn influences the rate of transpiration.
5. Water vapors are formed over the free surface. 5. Water vapors are formed in internal tissues.
