Question

why are there numerous layers of epidermis of the leaf ?

Answer 1

$\tt\blue{Hello\:Mate\:♥}$

The epidermis consists of the upper and lower epidermis; it aids in the regulation of gas exchange via stomata. The epidermis is one layer thick, but may have more layers to prevent transpiration. The cuticle is located outside the epidermis and protects against water loss; trichomes discourage predation.~
