表皮是叶子表面一种蜡一样的物质，随着叶子生长，因此观察叶子表皮和观察叶子最外层细胞——上皮——基本是一样的。

Cuticle is a waxy substance laid down on the leaf surface as it develops, so looking at leaf cuticle is essentially the same as looking at a leaf's outermost cells - the epidermis.

注意存在于表皮上皮细胞的淡紫色及粉红色的核内包涵体。

Notice the mauve to pink homogenous intranuclear inclusions in the epithelial cells of the epidermis.
