  1. Diversity Lesson : Fungi

  2. JOKES!!! • Why was the mushroom invited to the party? • Because he was a Fun Guy • Why did the fungi and algae get married? • They had a lichen for each other

  3. Characteristics • Once classified as Plant Kingdom due to cell wall • Cell walls containing chitin (same material used to make the exoskeleton of insects) • Heterotrophic: need to eat to obtain energy

  4. Structure • Fungi are diverse and widespread. • They are essential for the well-being of most terrestrial ecosystems b/c they break down organic material and recycle vital nutrients. Scale Cap Gills Spores Ring Stalk Vulva Fruit Body (generates spores) Mycelia (absorb nutrients from the soil)

  5. Structure of a Fungus • Structure has been adapted for two main functions: absorption of nutrients and reproduction • The majority of a fungus is in the form of a mycelium (branching structure) typically found underground • The visible part of the fungus is the reproductive structure (fruiting body) found above ground.

  6. Often the only visible parts of a fungus are its reproductive structures

  7. Types of Fungal Nutrition Fungi are heterotrophs (consumers):  They secrete exoenzymes that break down complex molecules and then they absorb the remaining smaller compounds as nutrients.

  8. Reproduction http://www.youtube.com/watch?v=5_rprVa-RY4

  9. Reproduction

  10. Examples of Fungi • Water moulds • Common moulds (e.g. bread) • Yeast • Mushrooms • Parasitic fungi

  11. Connection to Human Diseases • Ringworm • Athlete’s Foot • “Destroying Angel’s” • “Death Cap” (most dangerous)

  12. Connection to Plant Diseases About 30% of known fungal species are parasites, mostly on or in plants Corn Smut Tar spot fungus Ergots

  13. Importance of Fungi • Decomposer in nature’s recycling system • Yeast - makes bread, wine and beer • Penicillum produces antibiotic • Mushrooms - food items http://www.youtube.com/watch?v=5_rprVa-RY4

  14. Work • Read pp. 105-109 (Ch3 in the PDF) • Do Q19 – 23 on p.107 • Sketch fig. 3.16 on p.105
