In terms of structural materials, is to plants what is to lobsters and crabs. a. chitin; starch b. cellulose; chitin c. glycogen; cellulose d. monosaccharides; polysaccharides e. starch; glycogen

The correct answer is b. In terms of structural materials, cellulose is to plants what chitin is to lobsters and crabs. Cellulose is a structural component of the primary cell wall of the plants and it consists of long chain linked glucose units. Chitin is also made of glucose (polymer of N-acetylglucosamine). Chitin is a component of the exoskeletons of arthropods, like lobsters and crabs.
