BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The cell wall is composed of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides. In secondary cell walls, lignin may be deposited.

Detailed explanation-2: -Cellulose is the most significant structural component of plant cell wall. Cellulose, polysaccharide containing repeated unbranched (1-4) D-glucose units, is synthesized at the plasma membrane by the cellulose synthase complex (CSC) from bacteria to plants.

Detailed explanation-3: -Cellulose is the most abundant biopolymer, as it comprises the major structural component of the cell walls of lower and higher plants. We find high cellulose contents in stalks and stems and in other woody parts of plants.

Detailed explanation-4: -Cellulose is a complex carbohydrate polymer that contains oxygen, carbon, and hydrogen. The cellulose polymer is linear. The linear chain polymer comprises glucan, which is made up of around 10, 000 glucose units. These glucose units are linked together by a B-1, 4 glycosidic bond.
