The epithelial tissue is involved in a variety of functions in the body. Following are the most important functions. Protection is the main function of the epithelium. As an important component of the skin, the epithelium provides maximum protection to the body. Absorption in t..

A group of cells of the same type or of a mixed type having a common origin and performing similar functions are called tissues..

The cells always have a definite shape. They are either polygonal or cuboidal (isodiametric) or rectangular. Very rarely are the cells irregular. The cells are compactly arranged on a thin, structureless basement membrane which is secreted by the cells themselves. Due to the compact arrange..

The permanent tissues are formed by the differentiated cells, which become specialised to perform specific functions like protection, support, storage and conduction. The permanent tissues always differentiate from the meristematic cells, during the process of grow..

Permanent Tissues - Permanent tissues are derived from meristematic tissues. They have lost the power of dividing, having attained their definite form and size. In their earlier stages the cells are more or less similar in structure but slowly they become specialized a..
