Which of the following have cell walls made of chitin? Bacteria Animals Plants Fungi

Fungi are the champions here! Their cell walls are primarily composed of chitin, a tough and flexible substance that gives them structure and rigidity. Think of it as nature's own superhero armor, protecting these organisms and helping them thrive in various environments! On the flip side, you won't find chitin in bacteria, animals, or plants—those guys have their own unique structural materials. For instance, bacteria often have peptidoglycan in their cell walls, plants boast cellulose, and animals? Well, they skip the cell wall altogether because they have their own set of structural proteins!
