Question

what is one difference between cellulose and glucose? (1 point)
○ cellulose is made of glucose molecules while glucose is made of cellulose molecules.
○ glucose is not used to give structure to plants cell walls while cellulose is.
○ cellulose is formed by a chemical reaction while glucose is formed by a physical reaction.
○ glucose is a carbohydrate while cellulose is a protein.

Explanation:

• Analyze each option:
• First option: Incorrect. Cellulose is made of glucose molecules, but glucose is a monosaccharide, not made of cellulose.
• Second option: Correct. Glucose is a simple sugar used for energy, while cellulose (a polysaccharide of glucose) is a major component of plant cell walls, providing structure.
• Third option: Incorrect. Both cellulose (polymerization of glucose) and glucose - related reactions (e.g., photosynthesis to make glucose) involve chemical reactions.
• Fourth option: Incorrect. Both glucose (monosaccharide, a type of carbohydrate) and cellulose (polysaccharide, also a carbohydrate) are carbohydrates, not proteins.

Answer:

B. Glucose is not used to give structure to plants' cell walls while cellulose is.
