NEET BIOLOGY

Detailed explanation-1: -Stratified epithelia contain two or more layers of cells. The function of this type of epithelium is mostly protective-the higher the number of layers, the more protective it is. It is good at withstanding abrasion.

Detailed explanation-2: -Types of epithelial cells based on their arrangement Simple: A simple epithelium means that there’s only one layer of cells. Stratified: A stratified epithelium is made up of more than one layer of cells.

Detailed explanation-3: -Stratified epithelium consists of two or more cell layers. There is a great amount of variability between the layers due to various cellular shapes and heights. The three types of cellular shapes are squamous, cuboidal, and columnar.

Detailed explanation-4: -Stratified squamous epithelium consists of a single basal layer containing stem cells, 2–3 layers of proliferative basaloid cells in the suprabasal region, and larger keratinized cells toward the surface.

Detailed explanation-5: -Epithelia composed of a single layer of cells is called simple epithelia; epithelial tissue composed of multiple layers is called stratified epithelia.
