what is the meaning of the upper epidermis of a leaf?

I don't really understand by what you mean the meaning of the upper epidermis, but I'll give the function anyway. The upper epidermis has several functions. It protects against water loss, regulates gas exchange (there are only a few stomata on the uppermost layer of the leaf) and produces the waxy substance that becomes part of the cuticle.

This is a single layer of cells containing few or no chloroplasts. The cells are quite transparent and permit most of the light that strikes them to pass through to the underlying cells. The upper surface is covered with a waxy, waterproof cuticle, which serves to reduce water loss from the leaf.
