Sugars do not function only in the production and storage of cellular energy. They also can be used to make mechanical supports. Both plant and fungal cells gain structural support from cell walls composed of carbohydrate polymers. Compare the chemical component(s) of these cell walls.
A) Like plant cells, fungal cells possess a clews composed of cellulose.
B) Plant cell walls are composed of cellulose while fungal cell walls are composed of chitin.
C) Plant cell walls are composed of starch while fungal cell walls are composed of cellulose.
D) Plant cell walls are composed of cellulose while fungal cell walls are composed of a mixture of cellulose, starch and chitin.

B) Plant cell walls are composed of cellulose while fungal cell walls are composed of chitin.
Explanation:
- Sugars perform different functions in living organisms like production and storage of cellular energy, cell wall synthesis which provides mechanical support to the cell, etc.
- In plants, the cell wall is made up of cellulose which is an unbranched homopolymer of the D-glucose unit. The glucose unit is joined together by a β1-4 glycosidic linkage.
- In fungi the cell wall is made up of chitin and chitin is linear homopolysaccharide which is composed of N-acetyl-D-glucosamine residues which are joined through β1-4 glycosidic linkage.
