Presentation Transcript

  1. Fungi: Recyclers, Pathogens, Parasites, and Plant Partners

  2. DomainEukarya Kingdom Fungi Fungi are classified as a kingdom that is separate from plants, animals, and bacteria Fungi have cell walls that contain chitin, unlike the cell walls of plants, which contain cellulose. Phylum ……. (4) Phylogeny of Fungi

  3. Absorptive Heterotrophy • Ex: • Rhizopusstolonifer • Fungi secrete digestive enzymes, breaking down large food molecules in environment

  4. FUNGI • Common fungi: • yeasts • molds • mushrooms

  5. Important phylum of Kingdom Fungi • Phylum Chytridiomycota (chytrids) • Phylum Zygomycota (zygomycetes) • Phylum Ascomycota (ascomycetes) • Phylum Basidiomycota • (club fungi)

  6. Phylogeny of Fungi • Phylum Chyridiomycota • Oldest • Saprobic • Rhizoid – “root like” feeding organs • Live in fresh water/moist Env • Ex: Batrachochytriumdendrobatidis • Unknown mode.. • Keratin in skin? • Respiration affected

  7. Phylogeny of Fungi basidium – club shaped structure that develops during sexual reproduction • Most recognizable fungi Phylum – Basidiomycota Club – Fungi Fruiting body

  8. Structure of Fungi • Most fungi are mycelial (filamentous) *Cap/Pileus *Gills/Lamellae * Hyphae *Mycelium • My

  9. Phylogeny of Fungi • Zygospore Fungi • PhlyumZygomycota The name comes from zygosporangia, where resistant spherical spores are formed during sexual reproduction • 1,000 species • Arguably the most ecologically diverse group of fungi • Terrestrial • Soil, organic matter, poo

  10. Phylogeny of Fungi • PhlyumZygomycota • Pilobolus

  11. Phylogeny of Fungi • PhlyumZygomycota • Black bread mold • Rhizopusstolonifer

  12. Phylogeny of Fungi Phylum – Ascomycota Majority of fungal species (50,000) Ascus – sac like contain asopsores * Examples of sac fungi are yeasts , truffles,& penicillin

  13. Phylogeny of Fungi • Phylum – Ascomycota Sac Fungi or Sac Fungi *Terrestrial / free-living • Ascus – fingerlike sac that develops during sexual reproduction

  14. Phylogeny of Fungi • Phylum – Ascomycota • Yeast • Saccharomycescerevisia

  15. Phylogeny of Fungi • Phylum – Ascomycota • Clavicepspurpurea • Ergot –in grain • Clavicepspurpurea • Ergotism • Synthesizes LSD

  16. Phylogeny of Fungi • Ascomycetes –symbiotic relationships with algae to form…………

  17. Fungi as Symbionts • Lichen • an association between fungus and green alga. • Exact relationship is unknown.

  18. Fungi as Symbionts • Mycorrhizas • mutualistic relationships between soil and fungi

  19. Fun with Fungi • Farmers and zombies
