Understand that the question asks about the primary structural polysaccharide in fungal cell walls, which is a key component providing rigidity and shape.
Recall that cellulose is the main structural polysaccharide in plant cell walls, not fungal cell walls.
Recognize that peptidoglycan is a major component of bacterial cell walls, not fungal or eukaryotic cells.
Know that glycogen is a storage polysaccharide in animals and fungi, but it is not a structural component of the cell wall.
Identify chitin as the correct polysaccharide, which is a long-chain polymer of N-acetylglucosamine and provides structural support in fungal cell walls.
