Q

What is special about phylum chytridiomycota?

A

they are flagellated

17
Q

Phylum Zygomycota

A

haploid dominant life cycle
asexual: sporangium produces spores via mitosis (mitospores)
sexual: zygosporangium produces zygospores via meiosis (meiospores)

18
Q

Gametangia

A

gamete producing structures

19
Q

Phylum Glomeromycota

A

important plant mutualists

20
Q

Phylum Ascomycota

A

Haploid dominant life cycle
dikaryotic stage present during sexual reproduction
Asexual: conidiospores produced at end of hypha through mitosis (mitospores)
Sexual: ascospores produced on the ascoma through meiosis (meiospores)

21
Q

Phylum Basidiomycota

A

dikaryotic dominant life cycle
Asexual: most don’t do this
Sexual: basidiospores produced from basidia on the gills via meiosis
