plant cuticle is a kind of fat?

In biology, cuticle or cuticula is a tough but flexible, non-mineral covering of an organism, or part of an organism.

In zoology, the invertebrate cuticula is a multi-layered structure outside of epidermis of many invertebrates, notably roundworms and arthropods, where it forms an exoskeleton. It is formed by fatty acids with alcohols other than glycerol.

In botany, plant cuticles are protective waxy coverings produced by the epidermal cells of leaves, young shoots and all other aerial plant organs. The cuticles of plants help to prevent plants from drying out.

Therefore, plant cuticle is not a kind of fat but a little bit like wax.
