BIOL 2004 Study Guide - Final Guide: Zygomycota, Coenocyte, Choanoflagellate
Document Summary
Very diverse group of eukaryotes: some very small and unicellular, some produce large multicellular structures called fruiting bodies. Opisthakonts: closely related to animals and choanoflagellates. Nutrients and metabolism: composed of many cells, many produce reproductive fruiting bodies, sapotrophs, sapotrophs start with large molecules and break down into small organic, some are simple osmotrophs molecules using enzymes. Only consumer small organic molecules that don"t need further breaking down to be used. Generalities: most are aerobic, mostly immotile. Motile stage in life cycle: most are filamentous with hyphae. Mass of hyphae mycelium: reproduction. Sexual: different kind of spores sexual spores. Hyphae: individual elements of an organism are narrow made up of a bunch of very thin branching filaments. Lots of nutrient absorption: can grow at rates measured in tens of micrometers pper hour. Unicellular forms of fungi that have evolved in several lineages.
