Cellulose is polymer of: 

The aorrect answer is Glucose

Explanation:

• Cellulose is a polymer of β-D-glucose monomers. Each monomer is linked to the next by β(1→4) glycosidic bonds.
• This polysaccharide is a major component of the cell walls in plants
• It consists of linear chains of glucose units.

Other Options:

• Maltose: Maltose is a disaccharide composed of two glucose molecules linked by an α(1→4) glycosidic bond. It is produced from the enzymatic breakdown of starch.
• Sucrose: Sucrose is a disaccharide composed of one glucose molecule and one fructose molecule linked by an α(1→2) glycosidic bond. It is commonly known as table sugar.
• Fructose: Fructose is a monosaccharide, also known as fruit sugar. It is found in many plants and is one of the components of sucrose. Its chemical structure is different from glucose, and it is often used in combination with glucose in sweeteners.
