|
phylum chytridiomycota |
- distinguished by (2n) sporophyte stage in life cycle - make both sporangia & gametangia, but on separate "plants" - aseptate hyphae - sexual reproduction: zygosporangium produces endomeiospores - asexual reproduction: sporangium on sporangiophore (asexual hyphae) produces endomitospores - mainly (n) life cycle |
|
|
phylum ascomycota |
- distinguished by sexual spores being produced in sac-like "ascus" and asexual conidia - septate hyphae - asexual reproduction: hyphae grows conidiophore, (n) spores called conidia (exomitospores) grow off edges - sexual reproduction: many dikaryotic hyphae (n+n), karyogamy and meiosis occur in ascus, producing (2n) zygote that produce (n) endomeiospores
|
|
|
phylum basidomycota |
- distinguished by being "true mushrooms" - mushroom is called basidio - septate hyphae - most time spent in heterokaryotic stage - pileus (cap), stipe (stem), and gills (under pileus) - basidia produce 4 exomeiospores through karyogamy & meiosis |
|
|
hyphae |
tubular growth cells of fungi |
|
|
septate vs aseptate hyphae |
- septate: have "septum" dividing cells, allowing flow of cytoplasm and nutrients through mycelium - aseptate: form one long cell w/ many nuclei |
|
|
mycelium |
vegetative part of fungi; collection of hyphae |
|
|
decomposers |
break down dead material and consume them, usually using absorptive nutrition methods |
|
|
meiosporangia |
sporangium where meiosis occurs, producing (n) zoospores/meiospores |
|
|
mitosporangia |
sporangium where mitosis occurs, producing (2n) mitospores |
|
|
sporangiophore |
- asexual zygomycota reproduction - hyphae tips grow as upright stalks that form large swollen chamber (sporangium) separated from the mycellium by a complete septum called the columella |
|
|
zygosporangium |
- sexual zygomycota reproduction - when 2 different nuclei fuse from the progametangia, they form several (2n) zygote nuclei that develop in a thick-walled zygosporangium that goes through meiosis to produce endomeiospores |
|
|
budding |
- occurs in yeast - asexual - growth on parent cell - produces a genetically identical cell |
|
|
basidiocarp/basidium, basidiospores |
4 basidiospores (exomeiospores) are produced on the basidium/basidiocarp. basidia extend from the free surface of the gills |
|
|
lichen |
- symbiotic association b/w algae and fungi - crustose: crust/flat - foloise: leaves - fruticose: branches |
