Concept explainers
(a)
Interpretation: If the given characterisation can be applied to both cellulose and chitin, to cellulose only, to chitin only or to neither cellulose nor chitin has to be stated.
Concept introduction: Cellulose is the most abundant naturally occurring polysaccharide. The cell walls of plants are made up of cellulose. The second most abundant naturally occurring polysaccharide is chitin. It gives rigidity to most of the exoskeletons of crabs and lobsters.
