Detailed explanation-1: -Epithelial tissue cells can adopt shapes of varying complexity (from polyhedral to scutoidal to punakoidal), are tightly packed and form a continuous sheet. It has almost no intercellular spaces. All epithelia is usually separated from underlying tissues by an extracellular fibrous basement membrane.
Detailed explanation-2: -The tight arrangement of the cells leaves no intercellular space due to which the epidermis is able to provide protection against mechanical injury and pathogenic microbes. This layer also prevents water loss as no space is present between the cells.
Detailed explanation-3: -Epithelial cells are continuous and held tightly with no intercellular spaces between them. The cells of the epithelial are held by adhering junctions and tight junctions.
Detailed explanation-4: -Here, every cell is in direct contact with the underlying basement membrane. The five characteristics of epithelium are cellularity, polarity, attachment, vascularity, and regeneration.
