Eukaryotic
 Multicellular
 Heterotrophic
 Digest food outside of their body then
absorb it

› Many are decomposers – recycle nutrients
› Many saprobes- obtain food from decaying
organic matter
› Some Symbionts - live mutualy with other
organisms

Symbionts
› Lichens: symbiosis between fungus and algae
 Resistant to cold and drought
 Can survive where few others can (rocks)
 Help early stages of soil formation

Parasites:
› Plant diseases: Mildew and rust
› Animal diseases: ringworm and yeast infection
Structures


Cell walls have chitin – complex carbohydrate
Mycelium – thick masses of hyphae
Fruiting body
Hyphae
Mycelium

Hyphae
› Thin filaments only one cell thick which
compose the bodies of multicellular fungi

Fruiting Body
› Many produce spores which germinate to
form new fungi
Molds, yeast (sac fungi),
mushroom (club fungi), Penicillium
(imperfect fungi)
 May cause athletes foot and
ringworm


By structure and reproduction method

Phylum Zygomycota
› Sexual and asexual
› Life cycle include zygospore
› Common molds, bread molds
› Hyphae generally lack cell wall

Phylum Ascomycota
› Sexual and asexual
› Conidia, ascus, ascospores
› Largest phylum in Kingdom
› Some are large enough to be seen (morels)
› Others are microscopic (Yeast)
› Sac Fungi

Phylum Basidomycota
› Sexual reproduction
› Basidium and basidiospores
› Most elaborate life cycle
› Club Fungi (includes mushrooms), shelf fungi,
and puffballs
 Spores produce mycelium (grows
underground)
 With right conditions, fruiting bodies grow
above ground to produce spores

Phylum Deuteromycota
› Placed here because scientist don’t know
how they reproduce
› Extremely varied
› Imperfect fungi
