83. Cellulose, the most important constituent of plant cell wall is made of
[1998]
(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 : c
Hints & Solutions
(c) Cellulose is the structural polysaccharide of plant cell walls. They are long chain polymers of $\beta$-glucose units. The adjacent $\beta$-glucose units are joined by linkages.
