Vedclass · Answer

(A) The most significant physiological feature of stomata is their response to light.Generally,stomata open in the daytime (i.e.,in the presence of light) and close at night or in darkness. These are called photoactive stomata.However,in succulent plants like $Kalanchoe$ of the family $Crassulaceae$,the stomata open at night and close during the daytime.Such stomata are called scotoactive stomata.Since light is the primary environmental factor influencing the opening and closing mechanism in most plants,it is the main regulator.
