Question
Write major functions of stomata present in the epidermis.
Solution
Major Functions of Stomata are:
(i) Stomata are essential for exchange of gases between the plant and the atmosphere.
(ii) Normally, plants eleminate excessive water in the form of vapour through stomatal openings. The process is called Transpiration.
(iii) When there is shortage of water, stomatal openings get closed to reduce water loss. Stomatal openings also close down during night. Thus, stomata regulate water loss from plants i.e., they regulate transpiration.
