Q

Characteristics of Fungi

A
  • Eukaryotic
  • Cell wall of Chitin (heavy polysaccharide)
  • Heterotrophic
  • Some are parasites (ergot - wheat, corn smut)
  • excellent Decomposer
    • Converts organic matter into inorganic matter
    • Recycles nutrients back into environment
  • Can do Extracellular Digestion
    • (see follow on card for Extracellular Digestion)
  • Most parasitic fungi are parasitic of plants (few on animals)
  • Asexual and sexual reproduction
  • 1 million yet to be identified, most in soil.
2
Q

Structures of Fungi

A
  • Spores
    • Mostly non-motile (except zoospores in Chytridio)
    • Haploid
    • Reproductive structures
    • Found in spore sac
  • Hyphae (hyphal filament)
    • Threadlike filaments
    • Collected creates mycelium
  • Mycelium
    • Mass of Hyphae
    • Within the soil / wood (not seen)
  • Fruiting body (collected hyphae above ground)
    • Cap
    • Gills
    • Spores
3
Q

Extracellular Digestion (Fungi)

A

(Characteristic of Fungi)

  • Releases digestive enzyme
  • Enzyme breaks down organic matter
  • Matter releases nutrients
  • Fungus / other plants feed on nutrients
4
Q

Fungi parasitic to humans

A
  • Athlete’s Foot
  • Thrush (mouth)
  • Yeast infections
5
Q

2 Major groups of Fungi

A
  • Myxomycota
    • Water / slime molds
  • Eumycota “true fungi”
    • Chytridiomycota
    • Zygomycota
    • Ascomycota
    • Basidiomycota
6
Q

Chytridiomycota

A
  • Oldest of fungal groups
  • 1000 known in phylum
  • Flagellated Zoospores(motile)
  • Powerful decomposers
  • Can digest cellulose, keratin, and chitin
  • Partially responsible for decline in some amphibians
    • (skin lesions on frogs, reduces frog skin’s gas exchange ability)
  • E.g. Allomyces
