Verified step by step guidance1
Understand the definition of a structural polysaccharide: Structural polysaccharides are carbohydrates that provide structural support to cells and tissues. They are typically found in the cell walls of plants and exoskeletons of arthropods.
Identify the common structural polysaccharides: The most well-known structural polysaccharides are cellulose, found in plant cell walls, and chitin, found in the exoskeletons of arthropods and fungi cell walls.
Differentiate between storage and structural polysaccharides: Storage polysaccharides, such as glycogen and starch, are used for energy storage in animals and plants, respectively, whereas structural polysaccharides provide support and protection.
Analyze the options given: Glycogen and starch are storage polysaccharides, while cellulose and chitin are structural polysaccharides.
Conclude which options are structural polysaccharides: Based on the analysis, cellulose and chitin are the structural polysaccharides among the given options.
