Cellulose is found in _______.

Cellulose is found in _______.

• A. Animal connective tissue
• B. Plant cell walls
• C. Bacterial cell membranes
• D. Fungal cell walls

Answer: (B)

Cellulose is a structural polysaccharide that forms the main framework of plant cell walls, giving plants rigidity and strength. It’s made of long chains of glucose linked by β-1,4 bonds that align to create strong, fibrous microfibrils. Animals don’t synthesize or utilize cellulose in tissues like connective tissue; instead that tissue is built from proteins such as collagen. Bacterial membranes aren’t composed of cellulose—their walls are made from peptidoglycan (in most bacteria) or other coatings, not cellulose. Fungi use chitin (with glucans) in their cell walls rather than cellulose. So plant cell walls are where cellulose is found.
