Consider the statements — identify the incorrect ones:
A. Inulin is a polymer of fructose.
B. Starch is present as storehouse of energy in plants.
C. Cellulose is a polymer of sucrose.
D. Chitin is a heteropolymer.
Choose the correct answer:

Correct option is A

Correct Answer: (a)
Explanation:
A (True): Inulin is a fructan — a polymer of fructose.
B (True): Starch is the primary storage polysaccharide in plants.
C (False): Cellulose is a polymer of glucose, not sucrose.
D (False): Chitin is a homopolymer of N-acetylglucosamine (repeating unit), so it is not a heteropolymer.
Information Booster:
Cellulose = β-1,4-linked glucose polymer — structural polysaccharide of cell walls.
Starch = amylose + amylopectin (α-glucose polymers) — energy reserve.
Inulin (fructan) is stored in many plants (e.g., chicory, Jerusalem artichoke).
Chitin = polymer of N-acetylglucosamine — forms exoskeletons and fungal cell walls.
Heteropolysaccharides (e.g., hemicellulose) contain different sugar monomers.
