fungi Flashcards
fungi defintion
eukaryotes, are confused as plants but are actually very important
lichens
pioneer organisms,arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.
importance of fungi
function in mycorrhiza, are endophytes, decomposers, and parasites of plants
endophyte functions
fungi live within other plants to stimulate growth and reproduction, provide nutrients, and increase photosynthesis
fescue grass
made cows sick due to fungi producing a toxin
decomposers/ biogeochemical transformers
lignin, lignocellulose, cellulose, keratin, mycoremediation
diseases due to fungi
chestnut blight, wheat rust, corn smut, dutch elm
why do fungi decompose more than bacteria?
They are eukaryotic
ergot
hallucinogenic compound
how are fungi classified based on reproduction
zygomycota (asexual/sexual)
Basidiomycota (mushrooms)
chytridiomycota (flagellated gametes)
imperfect fungi (sexual reproduction not observed)
glomeromycota - arbuscular mycorrhizae
zoosporic fungi
opisthosporidia
chytridiomycota
neocallismastigomycota
blastocladiomycota
zygomycetous fungi types
zoopagomycota, Glomeromycota, mucoromycota
dikarya
Basidiomycota, agaricomycotina, Ascomycota
have two nuclei per hyphae cell
life cycle of fungi
all of the hyphae together are mycelium with haploid nuclei
mycelium path
can go through plasmogamy (fusion of cytoplasm to form heterokaryote) or can go through asexual reproduction to produce spores
heterokaryotic stage
2 nuclei in hyphae, forms a diploid which goes through meiosis to produce spores
where are basidiospores found
gills of fungi
sacrophytes
decompose the plant
chytrid polyphagous
parasite of the euglena cell
foliose lichen
mutualistic fungi
penicilum
fungi important for antibiotics cleaved from citrus fruits
other uses of fungi
food/clothing
form of fungi
typically filamentous (multicellular with hyphae), but can also be unicellular
what happens when fungi go through cell division
nuclear envelope stays in tact
fungi cell wall
composed of chitin
septate vs aseptate hyphae
septate - have cross walls
aseptate - coenocytic ( no cross walls)
