Answer
Starch is a polymer of glucose linked by 1-4 α glycosidic linkage. Hence, the correct answer is option (c) starch.
Work Step by Step
Polysaccharides like starch and glycogen are storage forms of energy and they release energy during digestion.
Glycogen is storage carbohydrate of animals. They store glycogen in liver and muscles. Hence, option (a) is not correct. Chitin is a polysaccharide that makes the exoskeleton of certain arthropods. It is a polymer of N-acetylglucosamine, a derivative of glucose. Hence, option (b) is not correct. Cellulose is a polymer that is abundantly present in plant material. Though cellulose is most abundant, it is not used as a storage carbohydrate. Instead, it serves as a structural support to plants. Hence, option (d) is not correct.
Plants synthesize carbohydrates during photosynthesis. The carbohydrates are stored in several structures, in the form of starch. Starch is a polymer of glucose linked by 1-4 α glycosidic linkage. Hence, the correct answer is option (c) starch.
