Answer:
Desmosomes as structured are two adjacent attached cells formed in the cell membranes from protein plaques while connected by filaments. The function of separating an organism from its environment is performed by epithelial keratinocytes.
To protect the organism, the keratinocytes are connected by the desmosome filaments through adherence. The adhered keratinocyte / desmosome connection produces prekeratin, a fibrous protein that adds to the epidermis a soluble structure
