The cell walls of fungi are diverse among the taxonomic groups, but most contain chitin microfibrils embedded in a polysaccharide matrix and covered with a loose coating of additional molecules combining sugars and peptides (amino acid chains).
1 The structure of cell wall is similar to plants but chemically the fungi cell wall are composed of chitin. 2  Fungi are heterotrophic organisms. 3  They fungi digest the food first and then ingest the food, to accomplish this the fungi produce exoenzymes. 4  Fungi store their food as starch.
