cuticle
The outer surface of the leaf with a waxy coating is called the cuticle. The cuticle helps reduce water loss from the leaf and provides protection against pathogens and physical damage.
The outer surface of the leaf has a thin transparent waxy covering called the cuticle
it is the outer most layer of the leave and so covers the leave surface except at the stomata
The outer layer of a leaf's skin is called the waxy cuticle, or just cuticle. You could also include the next layer, the epidermis layer. Mostly, though, the leaf's skin is called the 'Leaf surface'.
The key features of simple leaf anatomy include a single blade, a main vein called the midrib, smaller veins branching out from the midrib, and a petiole that connects the leaf to the stem. The leaf is typically flat and thin, with a top surface called the adaxial surface and a bottom surface called the abaxial surface. The outer layer of the leaf is called the epidermis, which contains stomata for gas exchange and a waxy cuticle to prevent water loss.
The lipid that makes up a leaf cuticle is primarily waxes, specifically cutin. Cutin forms a hydrophobic barrier on the outer surface of the leaf, helping to prevent water loss and protect the leaf from environmental stresses.

The protective substance that restricts water loss from a leaf is called cuticle. It is a waxy layer on the outer surface of the leaf that helps to reduce water evaporation and protect the leaf from drying out.
