| thallus | body of fungus |
| mycelium | loosely organized mass of threadlike structures called hyphae |
| fungi cycle | haplotic |
| 2 forms of fungi nutrition | saprophytic & parasitic |
| saprophytic | dead/decaying matter |
| parasitic | living matter |
| fungi reproduction | asexual & sexual |
| asexual reproduction | mitotic cell division |
| sexual reproduction | plasmogamy & karyogamy |
| plasmogamy | 2 gametes show fusion of cytoplasm, produces dikaryotic cell if nuclei fail to unite |
| Karyogamy | when 2 nuclei fuse, produces a zygote |
| 3 major groups based on gross morphology | molds, yeasts, mushrooms, |
| molds | filamentous hayphae, multicellular |
| yeasts | unicellular w/blastospores(buds) |
| mushrooms | multicellular 3-D |
| 4 major phylums (classes of fungi) | zygomycota, ascomycota, basidiomycota, deuteromycota |
| deuteromycota | no sexual spores, other 3 have sexual spores |
