Question

difference between simple and stratified epithelial​

Answer 1

Answer:

Simple, pseudostratified, and stratified epithelium are three arrangements of the cells in the epithelial tissue. Epithelial tissue is one of the four basic types of tissue in animals. Epithelial tissue lines the cavity and the surfaces of organs and blood vessels throughout the animal body. Three principle shapes of epithelial cells can be identified: squamous, columnar, and cuboidal. The pseudostratified epithelium is composed of a single layer of epithelial cells of which the nuclei are arranged in different levels. The main difference between simple and stratified epithelium is that simple epithelium is composed of a single layer of cells while stratified epithelium is composed of multiple layers of cells.

Answer 2

Simple Epithelial tissues :

• Extremely Thin and flat tissues.

• They form a delicate lining of organs.

• They are found in oesophagus , lining of the mouth , alveoli present in lungs , layers of skin that prevent wear and tear.

Stratified Epithelial tissues :

• When layered square tissues pile up ; they form Stratified Epithelial tissues.

• They are also found in skin and form the same network with same function.

• They are not attached to the basement layer also called as Basement Membrane .
