Fungal cell walls are composed of chitin. See fig. 22-3 Deuteromycetes; the imperfect fungi (?) Chytridiomycetes Zygomycetes – never see a dikaryotic stage (2 arrangements of chromosomes, 2 nuclei in each cell) Ascomycetes –ascospores Basidiomycetes – bacidiospores See fig.25-3 Kingdom Fungi Characteristics o Heterotrophic Extracellular digestion Decomposers (most); many mutualists, some parasites o Grow best in moist environments (air and food) Many can grow in o Concentrated salt solutions o Sugar solutions, e.g. jelly Fungi tolerate wide temperature range Prefer acidic pH (~5.6) o Can live pH 2-9 Fungal Anatomy Cell wall = chitin 2 body forms o Yeast Single-celled o Mold Multi-cellular Germination of a spore to form a mycelium See fig. 25-2, fig. 25-1 Chain of cells – hypha Mycelium – network of hyphae Spore – reproductive cell Some divided by septa (sing. Septum) – called septate
