Understand that the question asks about the primary composition of the fungal cell wall, which is a structural component external to the plasma membrane.
Recall that different organisms have distinct cell wall compositions: for example, bacterial cell walls are mainly made of peptidoglycan, plant cell walls are primarily cellulose, and fungal cell walls have a unique composition.
Identify that the fungal cell wall is not made of phospholipid bilayers with sterols, as this describes the plasma membrane, not the cell wall.
Recognize that peptidoglycan (murein) is characteristic of bacterial cell walls, so it is not the main component of fungal cell walls.
Conclude that the fungal cell wall is primarily composed of chitin, a polysaccharide that provides rigidity and structural support.
