Question

Describe the process of respiration in leaves of a plant.

Answer 1

 In leaves the exchange of respiratory gases takes place through very small pores called stomata(singular stoma). The stomata are present in large number on the lower surface of leaves of plant. Each stoma has a pore at its centre which is surrounded and controlled by two kidney shaped cells called guard cells. When the stoma opens the exchange of gases takes place between the atmosphere and interior of the leaf by the process of diffusion.
