EPIDERMIS. The skin or outer layer of cells of the 

 leaves and younger stems of plants. Jt usually consists 

 of a hardened cuticle, beneath which are cells holding 

 water but no chlorophyll or leaf green. The epidermis 

 is furnished with pores known as stomata, most often on 

 the undersurface of leaves, and on young stems, but 

 some leaves have them on both surfaces.
