Fungi can be unicellular or multicellular organisms.They are eukaryotic so have a nucleus and membrane-bound organelles.They are non-motile and have no mechanism for movement.The body or mycelium is made of threads called hyphae.The cell wall is made of chitin which is a polymer of N-Acetyl glucosamine.They have no chlorophyll or chloroplasts and are saprophytic (saprophytes) i.e. feed on dead and decaying organisms.They acquire nutrients by extracellular digestion and absorption of the soluble products.
