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 polysaccharide composed of a linear chain of -1, 4 linked d-glucose units with a degree of polymerization ranged from several hundreds to over ten thousands, which is the most abundant organic polymer on the earth.
Detailed explanation-3: -Cellulose is the primary structural component responsible for much of the mechanical strength of the cell wall. The distribution and orientation of cellulose microfibrils within the cell wall contribute to the control of cell growth.
Detailed explanation-4: -Starch is a plant polysaccharide that is predominantly found in cereal grains, roots and tubers such as potatoes, cassava and manioc, and legumes such as peas, chickpeas and beans (Table 1).
