fungi phyla
| Term | Definition |
|---|---|
| Ascomycetes | a phylum of fungi that produce sexual spores in saclike asci located at the surfaces of fruiting bodies known as ascocarps; also includes yeast |
| Basdiomycetes | a phylum of fungi that reproduce sexually; meiosis occurs in basidium to produce basidiospores; examples include cup fungus and mushrooms |
| primary mycelium | A mycelium in which the cells are monokaryotic and haploid; a mycelium that grows from either an ascospore or a basidiospore. |
| secondary mycelium | a dikaryotic mycelium formed by the fusion of two primary hyphae |
| Glomeromycota | a group of fungi that form mutualistic relationships with the roots of plants; arbuscular mycorrhizae |
| Zygomycota | Group of fungi that produce a zygospore during sexual reproduction and sporangiospores during asexual reproduction; examples include bread mold (Rhizopus) |
| Chytridiomycota | Group of aquatic fungi with flagellated zoospores; associated with the kill off of amphibians |
| Blastocladiomycota | Group of fungi with zoospores; exhibit alternation of generations similar to plants |
| Neocallimastigomycota | Group of fungi found in animal guts aide in break down of cellulose and lignin; contain the enzyme cellulase; lack true mitochondria (hydrogenosomes instead) |
| Microsporidia | fungi that are intracellular parasites; lack mitochondria; previously classified as a protist |
| Karyogamy | Fusion of two haploid nuclei to form a diploid nucleus. Occurs in many fungi, and in animals and plants during fertilization of gametes |
| Chitosan | polysaccharide derived from chitin found in the cell walls of zygomycetes |
| S. cerevisiae | Ascomycete known as budding yeast; used in the brewing of beer and wine, and in baking; important model organism used in biomedical research |
| Conidia | Asexual fungi spores of Ascomycetes |
| Basidiocarp | Elaborate fruiting body of a dikaryotic mycelium of a club fungus (basidiomycota). |
| ascus (asci) | the structure in which the haploid ascospores are formed in the phylum Ascomycota |
