Presentation Transcript

  1. Heterotrophic Absorptive, extracellular digestive via dig. enzymes Primary decomposers Along with bacteria Most are Saprobes Some parasitic Some predatory Some form symbiotic relationships All are spore formers Kingdom Fungi

  2. Most are multicellular (except for yeasts) • Extending filaments = hyphae • Branch network of hyphae = mycelium • Mostly coenocytic with reduced or partial internal septa (internal cell walls) • Cell walls with chitin • Nitrogenous polysaccharide

  3. 3-stage life cycle 1. Haploid stage Mycelia of “+” hyphae (n) and “-” hyphae (n) 2. Dikaryon stage (+) hyphae partially fuses with (-) hyphae producing a dikaryon (2 nuclei) or heterokaryon (more than two of each unfused nuclei) ** Some fungi will fuse the nuclei here and produce a zygote 3. Diploid stage fusing of the dikaryon (or heterokaryon) nuclei product of Karyogamy

  4. Rhizopus hyphae

  5. Zygomycota/Rhizopus sporangia

  6. Rhizopus zygosporangia

  7. Rhizopus zygosporangium 2 Zygosporangium(zygospores within) Suspensor cell

  8. Ecological roles • Saprobes, detritivores, recycle nutrients • Symbiotic • Mutualistic, parasitic, and predatory • Nitrogen fixing • Mycorrhizae fungi transfer essential minerals to roots in exchange for food • Can order spore inoculants to add to planting soil • Lichens

  9. Evolutionary branch of a flagellated ancestor • Fungal clades/ phyla based primarily on reproductive variations • Strategies • Morphological

  10. Basidiomycota-mushrooms

  11. Basidomycota-puffballs

  12. Basidomycota-bracket fungi

  13. Basidomycota-section through basidocarp Gills with basidia and basidiospores Stalk

  14. Basidospores on gills of basidocarp basidospores basidia

  15. Ascomycota/Hemisacomycota-Yeast

  16. Ascomycota/Euascomycota-Morels

  17. Ascomycota/Euascomycota-cup fungi

  18. Ascomycota, cup sectioned

  19. Ascospores with ascosporangia

  20. Penicillium Conidophore Conidiospores (conidia)

  21. Aspergillius

  22. Lichen structure 2 Asci with ascospores Algal cells

  23. Crustose lichen

  24. Fruticose lichen

  25. Foliose lichen

  26. Lichen soredia

  27. Lichen producing soredia along margin of thallus
