Detailed explanation-1: -Polysaccharides may be very large molecules. Starch, glycogen, cellulose, and chitin are examples of polysaccharides.
Detailed explanation-2: -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-3: -Starch and cellulose are two important examples of carbohydrates. Carbohydrates are a group of macromolecules that are made of sugar and can provide structure and support for cells, as well as acting as a source of quick energy.
Detailed explanation-4: -Cellulose [(C6H10O5)n] is a natural organic compound that is the most abundant biopolymer on the planet. It is a polysaccharide or complex carbohydrate made up of hundreds to thousands of glucose molecules linked together to form a chain.
Detailed explanation-5: -Cellulose is an important structural component of the cell walls of plants and many algae. Human uses of cellulose include the production of cardboard and paper, which consist mostly of cellulose from wood and cotton. The cotton fibers pictured below are about 90 percent cellulose.
