Biology Test 3
| Question | Answer |
|---|---|
| amoebozoans | -have lobe or tube shaped pseudopodia (lobopodia) -unicellular, colonial, and multicellular -heterotrophs -amoeboid movement -amoeboid feeding |
| plasmodium slime molds (amoebozoans) | -fungal-like -heterotrophs -no cell wall, move as a plasmodium -500 species -many are detrivores: break down dead organic material -multinucleate but not multicellular (mitosis, no cytoplasm) -amoeboid like streaming of cytoplasm |
| cellular slime molds (amoebozoans) | -feed as solitary amoeboid cells -cells can aggregate into a slug structure when food is scarce -cells remain separated by plasma membrane -show cell sacrifice (stalk cells will die) -cheaters can be present that will never be the stalk |
| amoebas (amoebozoans) | -heterotrophic, engulf food via phagocytosis -free living (soil, water) some are parasites -consume bacteria and other "protists" -entamoeba histolytica causes dysentary (spreads in contaminated food and water), (kills 100,000 people/year) |
| common characteristics shared by fungi | -chitin cell walls -heterotrophs, absorb nutrients, secrete hydrolytic enzymes -filamentous growth form, hypha (hyphae, mycelium, mushroom) -most non-motile, exception is the chytrids -many have a dikaryon (n+n) stage -multicellular, exception is yea |
| unikonts | one flagellum on posterior end |
