BIOMOLECULES AND ENZYMES

Detailed explanation-1: -In the cell walls of higher plants, the tensile fibers are made from the polysaccharide cellulose, the most abundant organic macromolecule on Earth, tightly linked into a network by cross-linking glycans.

Detailed explanation-2: -All cell walls of higher plants contain cellulose, a homopolymer of -1, 4-linked glucose units, mainly in the form of crystalline microfibrils as well as in an amorphous form (Carpita and McCann, 2000).

Detailed explanation-3: -Cellulose, a fibrous carbohydrate found in all plants, is the structural component of plant cell walls. Because the earth is covered with vegetation, cellulose is the most abundant of all carbohydrates, accounting for over 50% of all the carbon found in the vegetable kingdom.

Detailed explanation-4: -In the primary (growing) plant cell wall, the major carbohydrates are cellulose, hemicellulose and pectin. The cellulose microfibrils are linked via hemicellulosic tethers to form the cellulose-hemicellulose network, which is embedded in the pectin matrix.

Detailed explanation-5: -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.).
