Guida verificata passo dopo passo1
Identify the function of each polysaccharide listed in the options: Glycogen, Chitin, Cellulose, and Starch.
Understand that Glycogen is primarily used for energy storage in animals, not for structural support.
Recognize that Chitin is a structural polysaccharide, but it is found in the exoskeletons of arthropods and fungal cell walls, not in plants.
Recall that Starch is used for energy storage in plants, not for structural support.
Conclude that Cellulose is the polysaccharide that provides structure and support in a plant's cell wall, as it forms a rigid framework that helps maintain the plant's shape.
