Solution
(i) Stomatal transpiration: Stomata are minute pores confined to the epidermis of green shoot and leaves. The opening and closing of stomata are controlled by guard cells. Maximum loss (80-90 percent of the total water loss) of water from the plant tissues takes place through the stomatal opening.
(ii) Lenticular transpiration: Loss of water in the form of water vapour taking place through the lenticels present in woody stem and fruits is called lenticular transpiration. it amounts 1-5 percent of the total water loss by the plant.
(iii) Cuticular transpiration: the loss of water in the form of water vapour through the cuticle is known as cuticular Transpiration.
