NEET BIOLOGY

Detailed explanation-1: -The major constituents of the fungal cell wall are chitin, glucans, and glycoproteins. Chitin is a structurally important component of the fungal cell wall located closest to the plasma membrane.

Detailed explanation-2: -The cell wall is a characteristic structure of fungi and is composed mainly of glucans, chitin and glycoproteins.

Detailed explanation-3: -Fungal chitin is a component of the structural membranes and cell walls of mycelia, stalks, and spores. However, chitin is not found in all fungi and may be absent in one species that is closely related to another.

Detailed explanation-4: -Chitin is an essential component of the cell walls and septa of all pathogenic fungi, and occurs in the cyst walls of pathogenic amoebae, the egg-shells and gut lining of parasitic nematodes and the exoskeletons of invertebrate vectors of human disease including mosquitoes, sand flies, ticks and snails.

Detailed explanation-5: -20.8. Chitin, a biopolymer of N-acetylglucosamine with some glucosamine, is the main component of the cell walls of fungi, the exoskeletons of arthropods such as crustaceans and insects, the radulas of mollusks and the beaks of cephalopods.
