Biology Question

Introduction and Purpose of Lab

Kingdom Fungi has long been poorly understood at many levels (basic biology/life cycles, ecology, diversity, phylogeny) and we are now learning that Fungi is likely the most diverse of all the kingdoms. Fungi are also vitally important and intersect with most areas in biology. So whether you are interested in human/veterinary medicine, fungal ecology, full-blown mycology, or somewhere in-between – fungi are an important part of your field and investing a bit of time getting to know the fungi better could pay big dividends in your career.

Fungal phylogeny has long been in flux. We are only now sorting out a polyphyletic clade called the Deuteromycota that was essentially a catch-all bin for fungi who we did not know well enough to have identified their sexual stage. Thankfully, genetics and genomics have come to the rescue and we are refining the fungal tree of life (see Fig. 1, below). We will not be learning this updated phylogeny – I have not had time to review and learn it yet – so just keep in mind that some of the groups we will learn (e.g., Zygomycota) are now obsolete, at least for now. From your e-text, Ch 31:

Goals: Learn, Understand and Submit

• Understand
  • The classification (taxonomy) of select fungal clades.
  • The life-cycles, including sexual and asexual phases, of selected clades
• Learn
  • Important terminology used when studying fungi.
  • Morphology of selected fungal clades.
• Pre-Lab:

• • READ K101 Lab Exercise # 16: Morphology and Characteristics of Fungi with a focus on learning/understanding the bolded key terms and concepts.
  • COMPLETE K101 Lab Exercise #16: Morphology and Characteristics of Fungi Pre-lab write up
• Part 1: Complete K101 Lab Exercise #16: Morphology and Characteristics of Fungi in your K101 Lab manual.
  • Follow the procedures/instructions in your manual unless otherwise instructed by your Lab Instructional Team
  • Answer any questions within the lab.
  • Collect all the indicated data (photos/sketches of observations, numerical data, photos/sketches of your lab results, etc.)
  • Answer post-lab questions (if present)
• Part 2: Prepare your PowerPoint submission
  • Slide 1: Title Slide – include the name and # of the lab, your name, date, course info, and a credited image of your favorite fungi.
  • Slide 2: Chytridiomycota
    • READ:
      • (Natural History of Fungi) very basic page.
      • This was the best combination of up to date and ease of reading.
      • Sketch the lifecycle of Batrachochytrium dendrobatidis
  • Slide 3: Zygomycota (now Mucoromycota)
    • a pic of your labeled Zygomycota (now Mucoromycota) sketch
    • include (if present): hyphae, zygosporangium, asexual sporangium, suspensor
    • Note: make sure to include all Data Collection info where appropriate.
  • Slide 4: Ascomycota I – a pic of your labeled Peziza sketch
    • include (if present): hyphae, ascocarp, asci, ascospores
  • Slide 5: Ascomycota II / ‘Deuteromycota’ or ‘Imperfect Fungi’
    • pics of your Penicillium and Aspergillus sketches showing the conidiophores and conidiospores.
  • Slide 6: Glomeromycetes – (now Mucoromycota) a pic of your labeled Glomeromycetes sketch showing the arbuscular mycorrhizae.
    
  • Slide 7: Basidiomycota – a pic of your labeled Basidiomycota sketch
    • include: hyphae, basidiocarp, basidia, basidiospores, lamellae (gills)
  • Slide 8: Your favorite image from the fresh specimens in lab today. make sure to label as many structures as you are able to based on what you learned in lab.
  • Slide 9: Lichens a symbiotic mutualism – a pic of your labeled Umbillicaria sketch including algal cells, hyphae, upper cortex, lower cortex, soralium (w/ soredia), and apothecium (w/ asci and ascospores)
  • Slide 10: Reflection – Beneficial aspects of Fungi (provide 3 examples with links) OR Taxonomic Revisions
    • READ the first 6 paragraphs (up to and including the Resources Box) in
    • COMPARE the phylogeny and information presented there to what is shown in your current lecture text.
    • REFLECT on the two phylogenies by pointing out one major difference between the two phylogenies. Include an explanation of why they are different.
