Where can a cuticle be found on a plant?

cuticle: (adj. cuticular)


noncellular outer layer of an insect or a nematode; water-repellent, waxy layer of epidermal cells of plant parts, such as leaves, stems and fruit


(Upper: cuticle of root-knot nematode, Meloidogyne hapla) (Used by permission of Society of Nematologists); (lower: section view of a leaf)





if that helps at all...Where can a cuticle be found on a plant?
Plants produce a waxy, waterproof, outer layer to protect themselves from drying out. The wax lays across their epidermal cells. This cuticle is formed only by the plant's epidermal cells to shield its leaves and stems from dessication but it does not block the entry of light for photosynthesis.
