Dear student

A group of cells which is meant to perform a specific function is called tissue.imple tissues are composed of similar cells, while complex tissues are composed of different types of cells.

In biology, tissue is a cellular organisational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function.Simple epithelial tissues are generally classified by the shape of their cells.

The four major classes of simple epithelium are: 1) simple squamous; 2) simple cuboidal; 3) simple columnar; and 4) pseudostratified.

In humans, there are four basic types of tissue: epithelial, connective, muscular, and nervous tissue. There may be various sub-tissues within each of the primary tissues. Epithelial tissue covers the body surface and forms the lining for most internal cavities.
