Explanation:
Detailed explanation-1: -Stratified epithelium consists of two or more cell layers. Based on the shape of their most apical cell layer, they are further classified into squamous, cuboidal and columnar.
Detailed explanation-2: -Pseudostratified columnar epithelia are tissues formed by a single layer of cells that give the appearance of being made from multiple layers, especially when seen in cross section. The nuclei of these epithelial cells are at different levels leading to the illusion of being stratified.
Detailed explanation-3: -The nuclei are arranged at different levels in the layer of cells, making it appear as though there is more than one layer. This is called pseudostratified, columnar epithelia.
