Solution
The correct option is A Stomatal
Transpiration is the process of the escape of excess water from plants in the form of vapour through stomata. The rate of transpiration depends on the structural features of the plant organs and environmental factors. The number of leaves are more in plants as compared to other parts of the plants. Each leaf possesses numerous stomata. Xerophytic plants with their reduced leaf surfaces, thick cuticle, multiple epidermal layers, shrunken stomata, have structurally adapted so as to prevent loss of water to the minimum. Lenticels are the pores in the woody stem which is responsible for respiration and transpiration. Thus, the correct answer is option A.
