Kingdom: Fungi

Common Characteristics Eukaryotic Heterotrophic (external digestion) Cell Walls – Chitin Mostly Unicellular Some multicellular Hetertrophic: excretes enzymes and absorb nutrients Unicellular example: yeast Multicellular example:

Structure Fruiting Body Hyphae Mycelium (root-like) Fruiting Body: above ground – produces reproductive spores Hyphae: threadlike filaments (one cell thick) Mycelium: a network of hyphae below ground

Budding and Fragmentation Reproduction Asexual Budding and Fragmentation Sexual Spores Fragmentation: hyphae break off and grow new mycelia OR can go through budding Sexual: spores produced by fruiting body

Feeding Relationships Decomposers- Recycle Parasitism- Mildew, Yeast Infection, Athlete’s Foot Mutualism- Mycorrhizae- Fungus and plant roots Lichens-Fungi and algae or cyanobacteria Athletes foot, yeast infection, ringworm Bread-yeast, cheese, mushrooms

Penicillin (antibiotic) Importance Decomposer Penicillin (antibiotic) Food Source D: recycle nutrients P: used to create antibiotics yeast
