Final answer:
The dermal tissue of plants and human skin serve as protective layers, forming barriers against external threats.

In plants, the dermal tissue, mainly the epidermis, forms a barrier against mechanical damage, water loss, and pathogens, similar to how human skin protects against external threats. Both plant dermal tissue and human skin have adaptations like cuticle and keratin respectively, to fulfill their protective functions.
