Epidermis

Epidermis is the outermost protective layer. If you study the section of a leaf, many pores will be observed in the epidermis. These pores are stomata. 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.

The cells of epidermis are same as that of the other cells but  get modified on the outermost boundaries of the plant parts and form protective tissues that protect inner tissues. This outermost layer is initially one cell in thickness and is covered with cutin.

CuticleIt is a protective, waxy and hard layer present outside the epidermis. It is consist of a complex compound called as cutin.
