Transpiration is the lost of water in form of water vapour by plants to the atmosphere especially through the leaves if it is through the stomata it is called stomata transpiration. If it is through the lentil it is called lenticular transpiration.
Factors affecting the rate of transpiration
Increase in light intensity brings about an increase in the opening of the stomata. Hence increasing transpiration rate. Low light intensity reduces transpiration rate/
Temperature : An increase in temperature brings about an increase in a transpiration rate, since the atmosphere has a high capacity to hold water vapor. Low temperature bring about the decrease in transpiration rate.
Wind intensity: increase in wind intensity increases the rate of transpiration while transpiration rate decreases in a calm weather.
Humidity: This is the amount of water vapor the atmosphere can hold. Hight humidity reduces the rate of transpiration while low humidity increases transpiration rate.
Soil water: Plant surrounded by much water transpire than does surrounded by less water aquatic plant transpire faster than terrestrial plant. When the amount of water is low plant absorb H2O.
