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: -The plant cell wall is a dynamic network of several biopolymers and structural proteins including cellulose, pectin, hemicellulose and lignin. Cellulose is one of the main load bearing components of this complex, heterogeneous structure, and in this way, is an important regulator of cell wall growth and mechanics.

Detailed explanation-3: -Primary walls are comprised of 15–40% cellulose, 30–50% pectic polysaccharides, and 20–30% xyloglucans and lesser amounts of arabinoxylans and structural proteins, on a dry weight basis, structured into one or more lamellae.

Detailed explanation-4: -Cellulose, as the major component of plant biomass, is the most abundant polysaccharide in the world. Cellulose is a linear polymer consisting of -1, 4-linked D-glucose residues. These glucose chains are tightly bonded by hydrogen bonds to form insoluble fibrous materials.

Detailed explanation-5: -The secondary cell wall consists primarily of cellulose, along with other polysaccharides, lignin, and glycoprotein.
