Fungi

• non-motile
• heterotrophs
• extracellular digestion and absorption
• decomposers
• parasites

• Kingdom Fungi
• similarities to plants

4

• fungi have evolved in different direction

Plants Fungi
one nucleus per cell Often many nuclei per cell
autotrophs (have chlorophyll) heterotrophs
Starch - main storage molecule few or no storage molecules
have roots No roots
Cellulose in cell walls Chitin in cell walls (like insects)
reproduce by seed reproduce by spores

Fungi Structure Function

• hyphae
• chitin
• mycelium
• fruiting body

6
Fungal Feeding

• mycorrhizae
• Paul Stamets on 6 ways mushrooms can save the
  world Video on TED.com

Fungi Reproduction

• Asexual - spores
• Sexual - diploid zygospore

• Negative Roles of Fungus
• parasites
• foot fungus
• chytrid

• Positive Roles of Fungus
• decomposers
• foods
• antibiotics (penicillin)
• Lichens

Yeast

Major Phyla of Fungi
Phylum Reproductive Structure Examples
Zygomycota (common molds) Zygospores that contain sexual spores Black bread mold Pilobolus
Basidiomycota (club fungi) Club-shaped cell (basidium) contains sexual spores Mushrooms, puffballs, shelf fungi
Ascomycota (sac fungi) Sacs called asci that contain sexual spores Yeasts, truffles, morels
Chytrids Fungi with flagellated spores chytrids
11
Zygomycetes

• form a diploid spore (zygote)
• mycchorrhyzae

12
Basidomycetes Club Fungi

• Mushrooms
• rusts and smuts
• fruiting body
• rest of organism underground

13
Ascomycetes

• sac fungi produce spores
• morels
• penicillin
• yeast
