Due to a protective role, the epidermis forms a continuous layer. Inter-cellular spaces are absent. Stomata helps in the diffusion of gases in leaves.
Transpiration, i.e., loss of water vapour from leaves, also takes place through stomata. These pores are surrounded by two kidney-shaped guard cells which regulate the opening and closing of stomata.
