Fungi: Molds, Yeasts and Mushrooms Habitats diverse: aquatic in fresh water or marine, terrestrial in soil or on dead plant, a few are human parasitic Have rigid cell walls(resemble plant cell walls architecturally, not chemically) containing chitin(some with mannans, galactosan, chitosans instead of chitin) Fungal cell walls are 80-90% polysaccharide, with proteins, lipids, polyphosphates and inorganic ions making up the wall-cementing matrix

Thallus: the body or vegetative structure of a fungus Hypha(hyphae): long, branched, threadlike filament Mycelium: a tangled mass or tissurlike aggregation Coenocytic: hyphae that protoplasm streams through hyphae, uninterrupted by cross walls Septate: the hyphae have cross walls called septa with either a single pore or multiple pores that permit cytoplasmic streaming. (Septa: cross walls with either a single pore or multiple pores that permit cytoplasmic streaming
