  1. Fungi properties?
    -Do not perform photosynthesis. Are heterotrophs. Use enzymes to break down organic molecules. Then digests them later.
  2. Fungi: Morphology
    -Fungi consist of mycelia(strands), networks of branched hyphaeadapted for absorption. 

    -Most fungi have cell walls made of chitin
  3. Mycorrhizae
    • -are mutually beneficial relationships between fungi and plant roots.
    • -Ectomycorrhizal fungi has its hyphae over roots and in between cells.
    • -Arbuscular mycorrhizal fungi extends hyphae into plant cells.
  4. Fungi Sexual reproduction
    • Used to adapt to environments
    • Mycellum
    • Plasmogamy (fusion of cytoplast)
    • Heterokaryotic stage
    • Karyogamy (fusion of nuclei)
    • Meiosis
    • Sprores 
    • Germination
  5. Fungi asexual reproduction
    • Molds are visible mycelia
    • Some fungi like yeast undergo budding

    Spores are released by mycelium which then germinate when suitable ground is found.
  6. opisthokonts
    A clade of fungi, animals, and some protists.
  7. Zygomycetes (Zygomycota)
    -Produce zoospores. That are very resistant to conditions. Bread mold.
  8. Basidiomycetes
    A club like structure called a basidium. Also called club fungi. Mushroom.
  9. Asocomycetes
    • Fungi that live near or in water. Has sexual spores in a sac like asci that produces ascocarps.
    • Truffles.
  10. Ecological functions of fungi
    Decomposers and recyclers. Mutualistic relationships with plants (endophytes) such as protecting them from insects / toxins or breaking down objects. Termites have them for digestion.
  11. Lichen
    A symbiotic association between a photosynthetic organism and a fungus (usually Ascomycete). Algae provides carbon while cyanobacteria provides nitrogen fungi provide environmental growth.
  12. Mycosis
    A fungal pathogen.
  13. Penicillium
    A genus of ascomycetes that inhibits bacterial wall synthesis.
