Detailed explanation-1: -Cellulose is a polymer made with repeated glucose units bonded together by beta-linkages. Humans and many animals lack an enzyme to break the beta-linkages, so they do not digest cellulose.
Detailed explanation-2: -Cellulose is the most essential structural component of plant cell walls and the most common macromolecule and organic substance on the Earth. Cellulose is made up of carbohydrates which is a polysaccharide structure. Polysaccharide is made up of long chains of many sugar molecules that are chemically linked together.
Detailed explanation-3: -Cellulose is the main constituent of plant cell walls, so it is found in vegetables, fruits, cereals, and legumes; it coexists with hemicelluloses, pectin, and lignin. Cellulose is also the most abundant plant polysaccharide on earth, accounting for 15%–30% of the dry mass of all primary cell walls.
