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
