decomposers
Term
what can some fungi produce that are poisonous?
Definition
mycotoxins
Term
what are the five divisions of fungi
Definition
Chytridiomycota, Zygomycota, Ascomycota, Glomeromycota, and Basidiomycota
Term
which divisions are paraphyletic, monophyletic?
Definition
Chytridiomycota, Zygomycota v. Ascomycota, Basidiomycota, and Glomeromycota
Term
what is the storage polysaccharide of fungi?
Definition
glycogen
Term
can fungi engulf their food? why/why not?
Definition
no, chitinous cell wall
Term
how do fungi consume food?
Definition
release enzymes, then tips of hyphae absorb small nutrients
Term
coenocytic
Definition
aseptate, not divided into cells, multinucleate
Term
what are haustoria?
Definition
parasitic cell-penetrating hyphae
Term
what are rhizoids?
Definition
specialized hyphae that anchor onto the substrate
Term
two types of asexual reproduction practiced by fungi?
Definition
vegetative and sporic
Term
three types of sexual reproduction practiced by fungi, and which is the most common
Definition
*zygotic meiosis*, gametic meiosis, sporic meiosis
Term
heterokaryon
Definition
when plasmogamy is not immediately followed by karyogamy, have two nuclei
Term
dikaryon
Definition
if there are two different parent organisms in a heteorkaryon
Term
what are yeasts?
Definition
unicellular fungi
Term
what division are most yeasts in?
Definition
Ascomycota
Term
what is the brewing and baking yeast?
Definition
Saccharomyces cerevisiae
Term
are molds and yeasts taxonomic groups?
Definition
no
Term
which division of fungi have flagellated zoospores?
Definition
Chytridiomycota
Term
in which divisions of fungi are the hyphae coenocytic?
Definition
Chytridiomycota, Zygomycota, and Glomeromycota
Term
what are the zygomycota named for, what is it, and what is its ploidy?
Definition
the thick walled structure formed during sexual reproduction, called the zygosporangium, diploid
Term
what is the other name for Glomeromycota?
Definition
arbuscular mycorrhizal fungi
Term
describe the sexual and asexual reproduction of Zygomycota
Definition
asex: spores develop within sporangia
sex: zygosporangia formed by mating hyphae, creates sturdy diploid ready for dormancy

cellulose, gametic meiosis
Term
what are homothallic and heterothallic?
Definition
monoecious and dioecious for oomycetes
Term
other name for myxomycota?
Definition
plasmodial slime molds
Term
other name for dictyosteliomycota?
Definition
cellular slime molds
Term
Dictyosteliomycota: relation, food, cell walls, common reproduction?
Definition
amoebas, cellulosic, asexual spores
Term
Dictyosteliomyctoa, sexual reprod
