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.

Detailed explanation-2: -5.3. Cellulose, as is starch, is a carbohydrate. It is a structural polysaccharide, while starch is one of the storage polysaccharides. In terms of quantity, cellulose is the most represented polymer on Earth and is the main support for trees and other plants (cotton, flax, jute, sugarcane, cereals, etc.).

Detailed explanation-3: -Cellulose is the most abundant structural polysaccharide in plants, and it is responsible for the production of wood, paper, and cotton. In animals, chitin is an example of a structural polysaccharide that serves a structural function.

Detailed explanation-4: -Cellulose is the main polysaccharide in the plant cell wall.
