Fungus: Friend or Foe?
Fungi Facts • 400 Million Years Old • Heterotrophic • Biodiverse • Grow quickly
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.
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.
Fungi as Decomposers • Help clear dead plants, animals, and other wastes from environment. • Return valuable phosphorus, nitrogen, and other nutrients to soil.
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.
Spores • How do spores move away from the parent plant? • What do spores need in order to generate a new organism?
Examples of Fungi • Bread and food molds • How long does it take for fungus to grow on food? • What characteristics favor fungi growth?
Yeasts • What do you know about yeast? • What is fermentation and what products do we get from it?
Benefits of Fungi • Food source • Bread Baking • Cheese Production • Decomposers • Medicines • Penicillin • Cyclosporin
Negative Effects of Fungi • Destroy food sources • Breakdown plants and grasses • Human skin diseases • Athlete’s foot • Ringworm • Endocarditis (heart)
