What is cell wall? How it is formed?

Answered by admin @



Answer:

Cell wall is outermost covering of the plant cell . It is formed in such a way :

It occurs by a successive deposition of wall material, layer upon layer that is, by a process known as apposition. Growth of walls by apposition is usually centripetal, that is, it occurs from outside and toward the lumen of the cell. Centripetal growth is characteristic of cells forming tissues.
