what phylum contains mostly aquatic fungi?

chytridiomycota

what’s chytridiomycota’s significant feature?

it’s the only phylum that produces flagellated gametes

what is mycota used to do?

designate a phylum

what is mycetes used to do?

formally denote a class or used informally to refer to all members of the phylum

what phylum do chytrids belong?

chytridiomycota

what type of fungi are chytrids?

the simplest and most primitive Eumycota, or true fungi

do chytrids have chitin in their cell wall?

yes

are chytrids unicellular or multicellular?

most are unicellular

what do a few chytrids form ?

multicellular organisms

what kind of hyphae do chytrids have?

coenocytic hyphae

chytrids are the only fungi that…

have retained flagella, flagellates spores(zoospores) and gametes

what kind of decomposes are chytrids?

aquatic decomposers(saprobes) or parasites

what phylum do zygomycetes belong?

zygomycota

what does the sexual cycle of zygomyctes make?

a resistant zygosporangium

zygosporangium

structure that produces zygospores(sexual spores) which protect from desiccation or drying out

what kind of hyphae do zygomycetes have?

coenocytic hyphae

what are most species of zygomycetes?

saprobes

what are a few species of zygomycetes?

parasites, particularly of insects

how do zygomycetes reproduce?

usually asexually by producing sporangiospores (asexual spores)

what are the black spots of Rhizopus (sp. bread mold)

swollen sporangia

what phylum do ascomycetes belong?

ascomycota

what’s a significant feature of the phylum ascomycota?

it is the most diverse phylum and produces 2 types of spores

what 2 types of spores do ascomycetes produce?

ascospores(sexual spores) and conidiophores (asexual spores)

ascospores

w/in saclike ascus(plural asci)

conidiophores

released by conidiophores

what phylum do basidiomycetes belong?

basidiomycota

what’s a significant feature of the phylum basidiomycota?

most fungi that’s edible belong to this phylum

what are the spores of basidiomycetes?

sexual basidiospores produced by club-like basidium; more common than asexual

basidia

reproductive organs of basidiomycetes are often contained w/in the familiar mushroom

what phylum do glomeromyctes belong?

glomeromycota

describe glomeromcyetes relationship

mutualistic arbuscular mycorrhizae

mycorrhizae
