Document Summary
Mycelium -is the feeding network of a fungus. (see fig 22-1 a) Hyphae - the threadlike filaments of a fungus. (see fig 22-1 b) Chitin - a structural polysaccharide of modified sugars. The kingdom fungi consists of organisms that are eukaryotic and mainly multicellular. They are all heterotrophic decomposers that obtain their food by absorption. (kingdom fungi is most closely related to the animal kingdom) Most members of the kingdom fungi have several structural elements in common: This network may be very large but is usually underground or within the surface of a decaying organism. The mycelium is composed of a woven mesh of hyphae. These filaments are the building structure of the mycelium. They consist of a tubular cell wall containing chitin surrounding a plasma membrane and cytoplasm. In some fungi (coenocytic fungi) there are no separate cells and many nuclei are in a common cytoplasm.
