Cards

Term
Hyphae
Definition
Filaments
Term
mass of hyphae?
Definition
Mycelium ( the stuff under the reproductie structure!!
Term
Kingdom Fungi
Characteristics
Definition
Eukaryotic
Heterotrophic via absorption
Generally septate but can be coenocytic

Grow adding hyphal length not GEARTH
NUCLEAR ENVELOPE doesn't break down
Term
Saprobes
Definition
decomposers break stuff down (WOOD)
wasn't here for coal forming period
breakdown lignin by oxidising it (BURNING)
Term
Symbionts
Definition
insect guts to digest cellulose
Lichens
Mycorrhizae
Term
Mycorrhizae
Definition
help plant grow!!! needed for plant to grow in nature
Term
Ectomycorrhizal
type of mycorrhizal
Definition
Outside of plant, not in roots,
think north, nitrogen phosphorus
Term
Arbuscular mycorrhizal
Definition
tropics, phosphorous, LIVE INSIDE OF Root
Term
Endophytes
Definition
In leaf tissue, but not parasitic!! Just hang out
Term
What habitat do fungai like?
Definition
ideal, not in watter, terrestrial. Like warm, but wet not too much
Term
Fungai relatives?
Definition
Animals!
Term
Division Chytridomycota
Definition
single cell, Coenocytic hyphae
Saprobes (decomposers, and parasites)
ONLY FUNGI WITH FLAGELLATED STAGE
the true aquatic fungi
sporic meiosis! haploid and diploid
Term
coenocytic
Definition
Not cut into different cells
Term
Cyptic
Definition
cross section cell wall
Term
Septate
Definition
mean divided cells
Term
Division Zygomycota
Definition
BREAD MOLD
Hypahe - coenocytic and haploid
Zygotic meiosis
Can form asexual sporangia
2 hyphae come together to make zygote
Term
Division Glomeromycota
Definition
Hyphae - coenocytic
key to grassland success
ASEXUAL
Term
Division Ascomycota
Definition
cup fungi, sac fungi
hyphae- septate, haploid
YEASTS leaf "spots"
zygotic meiosis sorta
plasmogamy and karyogamy seperate
dikaryon
Nuclei fuse and meiosis occurs in an ascus
can produce asexual spores on conidia
Term
Dikaryon
Definition
N + N
Term
Ascus
Definition
long cell where meiosis occurs in asomycota
Term
ascocarp
Definition
3d version of ascus
Term
Division Basidiomycota
Definition
Club fungi
hyphae - septate haploid or dikaryon
MUSHROOMS!!
Lignin decomposers
Rust
Form mycorrhizae
Fairy Rings

Zygotic meiosis sort of
similar to ascomycetes, but dikaryon can grow and hang out.
Doesn't form asci immediatly.
Term
Lichens
Definition
Algae and fungas symbiosis
Alga is in the middle of fungal thallus
Fungus an ascomycete or basidiomycete
Usually with green algae
If conditions bad it can kick out the algae
HATE AIR POLLUTION
