mycelium
whole fungus
_ grow from spores and form the mycelium
hyphae filaments

mycelium
This Fungus Phylum has flagellated spores
Chytridiomycota
Another word for Phylum Chytridiomycota
water molds
May resemble first fungi to have evolved
Chytridiomycota
Aquatic fungi with flagellated zoospores
Chytrids
Most Chytrids are a, but some are b
decomposers, parasitic
linked to the decline of frog populations

common bread mold, belongs to phylum Zygomycota
Does Rhizopus produce asexual or sexual spores
both
Prudoced as Zygomycota fungus begins to grow and spread
asexual sporangia
_spores form as food is depleted
