Document Summary

Absorptive heterotrophs: release digestive enzyme, breaks down, absorbs. Most multicellular, some not, eg. yeast is unicellular. Found mostly underground: exposed to air lose water/die, reproductive structures above ground (fruiting structure) Made of hyphae, bunch of hyphae = mysilium. Long banched filament = hyphae increase surface area for efficient. Fruiting structure: produces spores (unicellular reproductive structures) by meiosis. Septate = cross walls, pores for diffusion of enzymes/organelles. Coenobytic = no cross walls, multiple nuclei but no divisons. Adapted for different jobs: eg. predation: release digestive enzymes. Adapted for different jobs: eg. predation: release digestive enzymes eg. parasitism. Adapted for different jobs: eg. predation: release digestive enzymes eg. parasitism eg. mutualism: mycorrhize = fungi associated with plant roots. Ecto: outside, endo: inside, fungus receives carbs, plant receives minerals and water. Fossils older than vascular plants of mychrorrhizae. Pioneer species, tundra animal food, break down rock with acid = soil.
