Detailed explanation-1: -Cellulose is the most abundant carbohydrate in the plant kingdom, forming the fundamental structure of plant cell walls, where cellulose is closely associated with other components such as hemicelluloses and lignin. Cellulose is distinguished from the starches by their 1 → 4 bonds.

Detailed explanation-2: -Plants store carbohydrates in long polysaccharides chains called starch, while animals store carbohydrates as the molecule glycogen.

Detailed explanation-3: -Cellulose is the most abundant natural biopolymer. The cell wall of plants is mostly made of cellulose; this provides structural support to the cell.

Detailed explanation-4: -Carbohydrates are a group of macromolecules that are a vital energy source for the cell, provide structural support to many organisms, and can be found on the surface of the cell as receptors or for cell recognition.
