Question

Cellulose, the most important constituent of plant cell wall is made of __________________.

• A. Unbranched chain of glucose molecules linked by $\alpha -1,4$ glycosidic bond
• B. Branched chain of glucose molecules linked by $\beta -1,4$ glycosidic bond in straight chain and $\alpha 1,6$ glycosidic bond at the site of branching
• C. Unbranched chain of glucose molecules linked by $\beta -1,4$ glycosidic bond
• D. Branched chain of glucose molecules linked by $\alpha -1,6$ glycosidic bond at the site of branching

Answer 1

The correct option is C Unbranched chain of glucose molecules linked by $\beta -1,4$ glycosidic bond

C. Unbranded chains of glucose molecules linked by β-1,4 glycosidic bond

Reason : Cellulose is the most abundant organic polymer found in the cell walls of plant cells. It is a polysaccharide and consists of long unbranched chains of glucose residues linked by β-1,4 glycosidic bonds. In plants, cellulose is produced from sugar. It serves as building material in the formation of cell wall.

So the correct option is C.
