Detailed explanation-1: -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-2: -The cell wall also provides the mechanical strength that allows plant cells to support the weight of other cells. The most abundant structural polysaccharide is cellulose. There is so much cellulose in the cell walls of plants that it is the most abundant of all biological molecules.

Detailed explanation-3: -In drought, a plant may wilt, but its cell walls help maintain the structural integrity of its stems, leaves, and other structures, despite a shrinking, less turgid vacuole. Plant cell walls are primarily made of cellulose, which is the most abundant macromolecule on Earth.

Detailed explanation-4: -Cellulose. The structural components of plants are formed primarily from cellulose. Wood is largely cellulose and lignin, while paper and cotton are nearly pure cellulose. Cellulose is a polymer made with repeated glucose units bonded together by beta-linkages.

Detailed explanation-5: -Three important polysaccharides, starch, glycogen, and cellulose, are composed of glucose. Starch and glycogen serve as short-term energy stores in plants and animals, respectively. The glucose monomers are linked by glycosidic bonds.
