Cuticle layer

The cuticle is a non-cellular protective layer covering the outer cell layer (epidermis) of the green, aerial parts of land plants.  Cuticles protect plants against dessication, UV radiation and various kinds of physical, chemical and (micro)biological agents.  Moreover, the cuticle also provides some support.  In fact, the cuticle  which protects the underlying tissues has basically the same function as our own skin.  In several groups of plants cuticles are very resistant and they have a high fossilization potential; only few groups do not generally have highly resistant cuticles (lycopods, Equisetophytes and ferns).
