Chitin is found in the cell walls of which organisms?

Explanation:
Chitin provides the rigidity for fungal cell walls. It’s a nitrogen-containing polysaccharide built from N-acetylglucosamine units that gives fungi their sturdy, adaptable walls. Plants have cell walls made mostly of cellulose, a glucose polymer. Bacteria have cell walls built from peptidoglycan, not chitin. Animals don’t have cell walls at all, relying instead on extracellular matrices for structure. Because chitin is the defining wall component in fungi, this group is where chitin is found in cell walls.
