Term
Phylum Chytridiomycota
Definition
Chytridiomycetes; Diploid asexual reproduction ; No dikaryon stage ; aquatic; flagellated; *only fungi with motile spores*
Term
Phylum Zygomycota
Definition
Zygomycetes; no septa between hyphae (except when forming sporangia & gametangia)
Term
Phylum Ascomycota
Definition
Ascomycetes; "Sac fungi"
Have ascus & ascocarp
Reproduce asexually by budding or binary fission
Term
Phylum Glomeromycota
Definition
Glomeromycetes; no septa between hyphae
No evidence of sexual reproduction
Term
Phylum Basidiomycota
Definition
Basidiomycetes; "Club fungi";
basidium and basidiocarps
Term
Deuteromycota
Definition
Deuteromycetes; "Imperfect fungi"
Polypheletic
Term
Alternation of Generations
Definition
Alternation of multicellular haploid and diploid forms
Term
Are most fungal cells haploid or diploid?
Definition
Haploid (N)
Term
Mycelia
Definition
masses of hyphae
Term
Septa
Definition
walls in fungi that form divisions
Term
Rhizoids
Definition
root like structures of fungi
Term
Hyphae
Definition
straw-like filaments in fungi
Term
Nuclear mitosis
Definition
spindle apparatus forms in nucleus & nuclear envelope divides after mitosis.
Term
Sporophyte
Definition
produces spores from sporangium for asexual reproduction (2N)
Term
Gametophyte
Definition
produces gametes from gametangium for sexual reproduction (N)
Term
Gametotangium
Definition
multicellular structure where gametes are formed
Term
Sporangium
Definition
multicellular organ in which meosis occurs and haploid cells develop.
Term
Dikaryon stage
Definition
(N + N) 2 haploid nuclei coexist in hyphae before fusing to make diploid nucleus
Term
Plasmogamy
Definition
fusion of 2 hypaes' cytoplasm
Term
Karyogamy
Definition
fusion of 2 haploid nuclei
Term
Monokaryotic
Definition
one nucleus in hypha (N or 2N)
Term
Dikaryotic
Definition
2N nuclei coexist before fusing to make a 2N nucleus
Term
Homokaryotic
Definition
hyphae whose nuclei are genetically similar genetically (same individual)
Term
Heterokaryotic
Definition
Dikaryotic or multinucleate hyphae with nuclei from different individuals
Term
Saprobe
Definition
absorb organic matter from non-living source (decomposer)
Term
Zygosproangia
Definition
temporarily dormant (until gametangia fuse) dikaryon stage with spore producing structures.
Term
Zygospores
Definition
sturdy, multinucleate structure where karyogamy and meosis occur
Term
Sporangiophore
Definition
clump of erect stalks produced by hyphae
Term
Ascus
Definition
sac shaped sexual spore producing structure
Term
Ascocarp
Definition
cup or morel structure of dikaryon stage
Term
Ascospores
Definition
8 haploid nuclei for sexual reproduction, produced by meosis and mitosis in ascus.
Term
conidia
Definition
asexual spores
Term
Conidiaspores
Definition
asexual spore producing structure
Term
Basidium
Definition
club shaped spore producing structures
Term
Basidiocarps
Definition
sexual spores; mushroom
Term
Faculitative symbiosis
Definition
nonessential for survival (partnership)
Term
Endophytic
Definition
live in intercellular spaces inside plants
Term
Arbuscular mycorrizae
Definition
hyphae penetrate root cell wall
Term
Ectomycorrizae
Definition
hyphae surround, but do not penetrate, cell walls
Term
Lichen
Definition
mutualistic symbiosis between fungus and photosynthetic partner (cyanobacteria or green algae)
Types: foliose, fruticose, crustose
