  1. Fungus: Friend or Foe?

  2. Fungi Facts • 400 Million Years Old • Heterotrophic • Biodiverse • Grow quickly

  3. Structural Information • Fungi are made up of tiny slender filaments called hyphae. • Cell walls contain chitin. • The central core of the fungus is often hidden in the soil, in wood or other food source.

  4. How do fungi survive? • Obtain energy and materials from living and dead organisms. • Secrete enzymes to break down food outside their bodies. • Absorbs nutrients from outside source.

  5. Fungi as Decomposers • Help clear dead plants, animals, and other wastes from environment. • Return valuable phosphorus, nitrogen, and other nutrients to soil.

  6. Fungi Reproduction • Fungi reproduce both asexually and sexually using cells called spores. • The part of the fungi you actually see are the spore structures. • A fungal spore is able to develop into a new organism.

  7. Spores • How do spores move away from the parent plant? • What do spores need in order to generate a new organism?

  8. Examples of Fungi • Bread and food molds • How long does it take for fungus to grow on food? • What characteristics favor fungi growth?

  9. Yeasts • What do you know about yeast? • What is fermentation and what products do we get from it?

  10. Benefits of Fungi • Food source • Bread Baking • Cheese Production • Decomposers • Medicines • Penicillin • Cyclosporin

  11. Negative Effects of Fungi • Destroy food sources • Breakdown plants and grasses • Human skin diseases • Athlete’s foot • Ringworm • Endocarditis (heart)
