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: -The plant cell wall is made up of cellulose which is a complex substance and provides structural strength to the plants. Q. Assertion :The exoskeleton of arthropods is made up of complex polysaccharide called chitin. Reason: Plant cell walls are made of cellulose.
Detailed explanation-4: -Final answer: Cell wall of bacteria is not made up of cellulose.
