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 |
