  • All fungi are eukaryotic heterotrophs that have
    rigid cell walls made of chitin
  • What is eukaryotic?
  • Fungi have a nucleus and membrane-bound organelle
    structures
  • What is a heterotroph?
  • Fungi get their food by eating other organisms or
    their byproducts and cannot make their own food

4
Fungi Characteristics       1) Unicellular and
Multicellular Eukaryote 2) Heterotrophs and
major Decomposers      3) Most reproduce
asexually by spores 4) Cell wall made of
Chitin 5) Need moist, warm places in which to
grow.

  • Fungi can either be unicellular or
    multicellular

Yeast is a single-celled fungus.
Witchs Hat fungus is multi-cellular.
6
  • The cells of fungi are arranged in branching,
    threadlike tubes called hyphae

Basidiomycete or Club Fungi

  • Fungi are heterotrophs, but they cannot catch or
    surround their food.
  • So, how do they eat?
  • They have to live near or actually on their food
    supply
  • There are 3 ways that fungi get their food
  • consumers (ex bracket fungus)
  • Decomposers (ex bread mold)
  • Parasites (ex zombie ants)

Reproduction
  • Most fungi reproduce asexually by making spores
  • Yeast cells reproduce asexually in a process
    called budding.
  • Fungi reproduce sexually when conditions are
    unfavorable.

11
The Role of Fungi in Nature
  • Food and Fungi
  • Yeasts make bread rise
  • Molds are used to make cheese
  • Mushrooms on pizza yum!
  • Environmental Recycling
  • Decomposersbreak down chemicals in dead
    organisms
  • Disease-Fighting
  • Penicillinbread mold that produces antibiotics
    which kill bacteria.
  • Disease-Causing
  • Athletes foot
  • Ring worm

12
  • Symbiosis Lichens
  • A fungus and algae or autotrophic bacteria living
    together in a mutualistic relationship
  • Fungus provides shelter, water, and minerals
  • Algae/bacteria provide food
