Cards in this set: Term state of DNA and acquisition of food of fungi Definition eukaryotic and heterotrophic Term are most fungi unicellular or multicellular? what's the exception? Definition multi, yeast Term what is the major ecological role of fungi? Definition 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 Term what are the terms for sexual reproduction of ascomycetes and basidiomycetes? Definition asci, ascocarp; basidia, basidiospores Term what are lichens?
