Detailed explanation-1: -Fungi are eukaryotes that lack chlorophyll and are heterotrophic. The body structure of fungi is unique. It is composed of branched and filamentous hyphae, which form a net-like structure known as mycelium. The hyphae have a thin, rigid wall made up chiefly of chitin, a nitrogen-containing polysaccharide.

Detailed explanation-2: -The pervasiveness of chitin is attributed to its use by diverse eukaryotic organisms, including fungi, insects, mollusks, crustaceans, algae, and protists. These diverged lineages commonly use chitin to strengthen their cell walls or skeletons.

Detailed explanation-3: -The cell wall is a characteristic structure of fungi and is composed mainly of glucans, chitin and glycoproteins. As the components of the fungal cell wall are not present in humans, this structure is an excellent target for antifungal therapy.

Detailed explanation-4: -Chitin and chitosan are not components of cell wall in all fungal species. The fungal classes of Basidiomycetes, Ascomycetes, Zygomycetes, and Deuteromycetes are known to contain chitin and chitosan in their cell walls.

Detailed explanation-5: -Fungi are usually subdivided into several groups according to the type of structural polysaccharides in their cell walls. The two best known types of cell wall polysaccharides possessing elicitor functions are -1, 3-glucans and chitins (or chitosan). True fungi contain chitin and glucan in the cell wall.
