Which of the following is a polysaccharide?

The polysaccharide among the options listed is cellulose. Carbohydrates are one of the main types of biomolecules in living organisms and they can be classified into three main groups: monosaccharides, disaccharides, and polysaccharides. Monosaccharides are simple sugars that cannot be further broken down into smaller sugars, while disaccharides are formed by two monosaccharides joined by a glycosidic bond. Polysaccharides are complex carbohydrates made up of many monosaccharide units linked together. They can be found in many biological structures, such as cell walls, energy storage molecules, and structural components. Glucose, sucrose, and maltose are all examples of simple sugars, and therefore not polysaccharides. Cellulose, on the other hand, is a polysaccharide that is an important structural component in the cell walls of plants and algae. It is composed of long chains of glucose molecules linked by β-glycosidic bonds, and it provides rigidity and strength to the cell wall.
