Chemical Composition of Cell Wall (With Diagram) | Plants

The cell wall is mainly composed of carbohydrate rich materials. The major components of cell wall are cellulose, pectins, hemicelluloses, proteins and phenolics. The cell wall is a biphasic structure consisting of relatively rigid cellulosic microfibril embedded in gel-like non-cellulosic matrix. The microfibrillar phase consists of only cellulose (β1, 4-glucan) and the matrix is composed of non-cellulosic polysaccharides and other [...]

Chemical Changes in the Cell Wall: 5 Phenomenon | Plants

The following points highlight the five phenomenon that takes place because of the chemical changes in the cell wall. The phenomenon are: 1. Lignification 2. Cutinization 3. Suberinization 4. Mineralization 5. Mucilaginous Change. Phenomenon # 1. Lignification: In this phenomenon lignin is the substance of impregnation. Lignin is a phenolic polymer and contains three subunits namely-coumaryl, guiacyl and sinapyl-propane. It [...]

Biochemical Pathways of Major Wall Component Formation | Plant Cell

In this article we will discuss about the three main biochemical pathways of major wall component formation. The biochemical pathways are: 1. Polysaccharides 2. Protein 3. Lignin. Biochemical Pathway # 1. Polysaccharides: They are synthesized from sugar nucleotides by polysaccharide synthases (Glycosyltransferase). The monosaccharides glucose, galactose, mannose, xylose, arabinose, glucuronic acid, galacturonic acid and fucose etc. compose the wall polysaccharides. [...]
