What is stomata????????
Answers
Answer:
In botany, a stoma, also called a stomate is a pore, found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening

Effect of humidity :- Under moist air conditions diffusion resistance decreases. When the stomata close at low air humidity the water content of the apricot leaves increases. The stomata open at high air humidity in spite of a decrease in leaf water content.
Purpose or function :- Stomata, the small pores on the surfaces of leaves and stalks, regulate the flow of gases in and out of leaves and thus plants as a whole. They adapt to local and global changes on all timescales from minutes to millennia.
Regulations:- The movements of the stomata are regulated by various environmental signals such as light, temperature, CO2, drought conditions and pathogens1,2. Among them, blue light, red light and low CO2 act as a positive signal for stomatal opening.
Average length:- Stomata also varied widely in size, with mean guard cell length ranging from 19.1 to 71.5 μm.
