  1. Fungi A guide to Chapter 7 Fungus (FUHN-guhs): plural Fungi (FUHN-jigh)

  2. Characteristics of Fungi • Range in size: Unicellular to Multicellular • Heterotrophs • Asexually reproduce by spores. • Made up of hyphae.

  3. Feeding • Fungi release chemicals that digest the substance on which they grow. • Then they absorb the digested food. • Decomposers

  4. Structure of Fungi • Unicellular (yeasts) • Multicellular (all others) • Hyphae: threadlike tubes that make up fungi. • They grow very quickly.

  5. Reproduction of Fungi • Reproduce by spores. • Tiny reproductive cells enclosed in a protective cell wall. • Can be carried by the wind. • Spores are produced in Fruiting Bodies.

  6. Forms of Fungi • Mushrooms • Yeasts • Molds

  7. Mushrooms • Shaped like umbrellas • Stalk • Ring • Cap • Gills (spores) • Can be poisonous.

  8. Yeasts • Unicellular • Used to make bread. • Produces carbon dioxide. • Reproduce by budding.

  9. Molds • Fuzzy, shapeless, flat. • Used to make food. Tofu, soy sauce and cheeses. • Provide valuable medicines. • Grow on food.

  10. Penicillin • Scottish scientist Sir Alexander Flemming. • 1928 • Discovered Penicillin from the mold called Penicillium. • Antibiotic

  11. Fungi and Disease • Damage and kill plants • Damage stored crops • Produce toxins in plants that can harm humans and animals. • Can be used as pesticides. • Ringworm, athlete’s foot, toenail fungus.

  12. Lichens • Two organisms living symbiotically. • Fungus and Alga • Alga is an autotroph without roots, stems or leaves. • The fungus provides the water and minerals.
