  1. General Biology II Lab Fungi

  2. The Domains • Domain Bacteria – unicellular prokaryotes • Bacteria • Cyanobacteria • Domain Archaea – unicellular prokaryotes • Domain Eukarya – eukaryotes • Kingdom Protista • Kingdom Fungi • Kingdom Plantae • Kingdom Animalia

  3. The Domains • Domain Bacteria – unicellular prokaryotes • Bacteria • Cyanobacteria • Domain Archaea – unicellular prokaryotes • Domain Eukarya – eukaryotes • 6 Supergroups • Protists are spread over these 6 Supergroups • Fungi and Animals are in SupergroupOpisthokonta • Plants are in SupergroupArcheaplastida

  4. Kingdom Fungi • Heterotrophs that absorb nutrients from surroundings • produce windblown spores both sexually and asexually • Spores develop into a mycelium • (collection of haploid spores called hyphae) • Sexual reproduction • Hyphae from 2 different individuals meet up to fuse and form a diploid nucleus • That diploid nucleus undergoes meiosis (remember from Bio 1, cell division reducing parent cells by ½) to produce spores • This meiosis occurs in a fruiting body (like a mushroom) depending on the species • Fungi cell walls = chitin (exoskeletons of arthropods)

  5. Kingdom Fungi • Zygomycota(Rhizopus) • Bread molds • Sexual repro = zygospore -> zygosproangium • Asexual repro = spores -> sporangium • Ascomycota (Saccharomyces, Penicillium, Aspergillus, Peziza) • Sac fungi, bread yeasts, common molds • Sexual repro = ascospores -> ascus • Asexual repro = conidia (spores) -> conidiophores • Basidomycota(Coprinus) • Mushrooms, puffballs • Sexual repro = basidium -> basidiospores • Asexual repro = “ “ candida (spores -> conidiophores • Lichens (ex. Mycorrhizae) • Symbiotic relationship between fungus and cyanobacterium • Fungus allows inorganic nutrients to enter the root, and the plant provides fungus with organic nutrients (products of photosynthesis).

  6. Kingdom Fungi • Zygomycota (Rhizopus) • Bread molds • Sexual repro = zygospore -> zygosproangium • Asexual repro = spores -> sporangium

  7. Phylum Zygomycota

  8. Kingdom Fungi • Ascomycota (Saccharomyces, Penicillium, Aspergillus, Peziza) • Sac fungi, bread yeasts, common molds • Sexual repro = ascospores -> ascus • Asexual repro = conidia (spores) -> conidiophores

  9. Domain Eukarya Kingdom Fungi Phylum Ascomycota

  10. Kingdom Fungi • Basidomycota (Coprinus) • Mushrooms, puffballs • Sexual repro = basidium -> basidiospores • Asexual repro = “ “ candida (spores -> conidiophores

  11. Phylum Basidiomycota

  12. Kingdom Fungi • Lichens (ex. Mycorrhizae) • Symbiotic relationship between fungus and cyanobacterium • Fungus allows inorganic nutrients to enter the root, and the plant provides fungus with organic nutrients (products of photosynthesis).

  13. Todays lab: • Exercise 3, pgs. 15-20 • Complete To Do on page 16 • Be very familiar with the life cycles on pages 17-19 for each Fungi Phylum you looked at today

  14. Make Notecards!!!!! • On one side write: • Domain • Kingdom • Group • Genus • Characteristics • Know what is prokaryotic and what is eukaryotic! • On the other side: • Picture of the organism • On Handout • Domain is CAPITALIZED • Group is in bold print • Genus is underlined (# is the slide #)
