  1. Kingdom Fungi I. General Characteristics 1. Found almost everywhere 2. Used to be classified as plants because they were anchored and have cell walls, but are now a distinct Kingdom.

  2. Structure of Fungi A. Structure of Fungi 1. Most fungi are Multicellular 2. Hyphae - threadlike filaments which develop from fungal spores 3. Mycelium - network of filaments (hyphae) 4. Chitin - complex carbohydrate which makes up the cell walls of fungi

  3. Mycelium - network of filaments (hyphae)

  4. Label the Mushroom Cap Gills Gills Basidia Stipe Stipe Hyphae Mycelium

  5. II. How Fungi get their Food • A. Extra cellular digestion • 1. Fungi are heterotrophs - which means they depend on other sources for supply of energy • 2. Extra cellular digestion- breakdown food outside of the cell by use of powerful enzymes • 3. Parasite fungi absorb nutrients from their hosts by using specialized hyphae called haustoria

  6. III. Reproduction • A. Fungi may reproduce asexually or sexually. Most produce spores which land on favorable conditions and grow. • B. Budding- a form of asexual reproduction where a new individual grows out and separates from parent cell. • C. Sporangium- a sac in which spores are produced

  7. IV. Fungi are divided into 4 phyla • A. Zygomycota (black bread mold)

  8. B. Ascomycota- Sac Fungi (blue-green, red & brown molds, morels & truffles, yeast)

  9. C. Basidiomycota- Club Fungi (mushrooms, puffballs, bracket fungi)

  10. D. Deuteromycota- imperfect fungi(Penicillium, athletes foot, ringworm)

  11. Symbiotic Relationships • 1. Mycorrhiza- Fungus in a symbiotic relationship with the roots of a plant

  12. 2. Lichens- a symbiotic association between fungus and a green alga or cyanobacteria • Fungus receives nutrients from plant and plants receive moisture & ground stability

  13. Fairy Ring
