    Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in humans, animals, and fungi. The polysaccharide structure represents the main storage form of glucose in the body. Glycogen is the analogue of starch, a glucose polymer that functions as energy storage in plants.

    Correct Option: B

    Utricularia (also called bladderworts) is a genus of carnivorous plants. They occur in fresh water and wet soil as terrestrial or aquatic species. All Utricularia are carnivorous and capture small organisms by means of bladder-like traps. Terrestrial species feed on protozoa and rotifers swimming in watersaturated soil’ while aquatic species feed on water fleas (Daphnia), nematodes and even fish fry, mosquito larvae and young tadpoles.

    It is during the pupa or cocoon stage that the silkworm yields the fiber of commercial use. As the silkworm prepares to pupate, it spins a protective cocoon. About the size and color of a cotton ball, the cocoon is constructed from one continuous strand of silk, perhaps 1.5 km long (nearly a mile). The silk cocoon serves as protection for the pupa.
