GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -Posted June 9, 2022. Yes, fungi have cell walls. All fungi, whether unicellular or multicellular, have a thick cell wall composed of tough complex polysaccharides called chitin. Chitin provides the cell walls of fungi with crucial structural strength.

Detailed explanation-3: -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.
