Stomata are the minute openings or tiny pores,presentin the epidermis of leaves. Stomata plays an important role by permitting theexchangeof gases such as oxygen, carbon dioxide, and water vapour to diffuse between the interior and outer surface of the plant tissues.
Transpiration is the biological process of removal of excess water from the aerial parts of the plants. An increase in temperature reduces the relative humidity of the atmosphere. This results in an increase in the rate of transpiration.
