The cell wall is a rigid, semi-permeable protective layer found as the outermost layer of many types of cells. Mainly it is composed of carbohydrate-rich materials such as cellulose, hemicellulose, pectins, proteins and phenolics.

Cellulosic cell walls are made of cellulose, which is a linear polysaccharide polymer with many glucose monosaccharide units. Only plant cells and few other exceptional organisms have cellulosic cell walls. Cellulose helps the cells to maintain their shape of plants and tolerate turgor pressure. 

An organism in which cellulose is absent in its cell wall has a non-cellulosic cell wall. Here instead of cellulose, the cell wall is made of pectin, chitins or hemicellulose—non-cellulosic cell wall act as pressure vessels, preventing the bursting of cells when water enters. The non-cellulosic cell wall is found in bacteria and fungi, where the cell wall of bacteria is made of peptidoglycan and that fungi are chitin. Pectin and hemicellulose as cell wall components are seen in most of the marine algae.
