The cell wall composition varies across kingdoms. Plant cell walls are primarily composed of cellulose, a complex polysaccharide. Fungal cell walls are characterized by the presence of chitin, providing structural rigidity. Bacterial cell walls consist of peptidoglycan (murein). Therefore, all three statements accurately describe the cell wall composition of these respective groups.

Ringworm (dermatophytosis) is a superficial fungal infection of the skin, hair, or nails. It is caused by dermatophyte fungi, primarily from the genera Microsporum, Trichophyton, and Epidermophyton. Despite the name, it is not caused by a worm. Aspergillus can cause aspergillosis, and Saccharomyces is yeast used in baking and brewing.
