The term that refers to the fact that an epithelial tissue has only one layer of cells is simple epithelial.

Explanation:

Epithelial tissues are thin tissues that cover all the exposed surfaces of our body.

Based on the number of cell layers, the simplest classification of epithelial tissue is:

a. Simple Epithelial Tissue

When the epithelial tissue consists of a single layer of cells, it is called simple epithelial tissue.

b. Stratified Epithelial Tissue

When there are two or more layers of cells in epithelial tissue, it is called stratified epithelial tissue.

Cuboidal epithelial is also a type of simple epithelial tissue.

Pseudostratified is another type of epithelial tissue which falls in neither simple nor stratified category. They consists of a single layer but the positioning suggests it is stratified.

There are 3 types of epithelial tissues based on their shape:

a. Squamos epithelial tissue

b. Cuboidal epithelial tissue

c. Columnar epithelial tissue
