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: -Cellulose is a fiber found in fruits, vegetables, and other plant foods as part of a plant’s cell walls. It’s found in tree bark and a plant’s leaves.

Detailed explanation-3: -The primary wall is the cellulose-containing layer laid down by cells that are dividing and growing. To allow for cell wall expansion during growth, primary walls are thinner and less rigid than those of cells that have stopped growing.

Detailed explanation-4: -Cellulose is a major component of plant cell walls, and is the world’s most abundant biopolymer. Cellulose contains apparently simple linear chains of glucose residues, but these chains aggregate to form immensely strong microfibrils.

Detailed explanation-5: -A plant cell wall is arranged in layers and contains cellulose microfibrils, hemicellulose, pectin, lignin, and soluble protein.
