Presentation Transcript

  1. Domain Archaebacteria Domain Eukaryotes Domain Bacteria Common ancestor Kingdom: Fungi Eukaryotes

  2. General characteristics • Classification criteria • eukaryotes • heterotrophs • must feed off of others • mostly multicellular • except one-celled yeasts • cell wall

  3. Structure • Cells • long thread-like cells • multiple nuclei • cell wall • made fromchitin • just like crab shells chitin cell wall septum pore nuclei

  4. How do Fungi get their Nutrition? fungal cells • Heterotrophs • secrete digestive enzymes • absorb digested material into cell • predators • paralyzing prey • parasites • feeding on living creatures • decomposer • breakdown dead remains plantcell wall plant cellmembrane plant cell Cool…Fungi live INtheir food! Chocolate cake,anyone?

  5. Ecological Roles • Decomposers • recycle nutrients • Symbiotic Relationships • lichen • fungi + algae • pioneer species in ecosystems • makes soil from bare rock • mycorrhizae • fungi + plants • enables plants to absorb more water

  6. Mycorrhizae • Critical role in plant growth • extends water absorption of roots withoutmycorrhizae withmycorrhizae Endomycorrhiza Ectomycorrhiza

  7. Reproduction • Asexual • budding in yeast • Sexual • spores • spread by wind gills onmushroom mushroom sporeson gills fungusgrowingin soil

  8. Fairy Rings

  9. Importance of fungi to humans • Food production • bread • beer, wine • Medicine production • antibiotics penicillin

  10. Any Questions??

  11. Zygomycete (Bread Mold) Life Cycle spores mating strain hypha sporangium MEIOSIS mating strain (2n)diploid (n)haploid FUSION of gametangia
