Chapters 26 and 28 (Taxonomy and Protists)
| Question | Answer |
|---|---|
| Binomial nomenclature | The system of taxonomy that scientists use to describe species |
| Species | most basic unit of classification |
| Kingdom Animalia | Protozoans |
| Kingdom Plantae | Bacteria/fungi (cell walls/no mobility), any unicellular, ps organism |
| 1969 Whittaker's 5-Kingdom | Prokaryotes (monera), protista, fungi, plantae, animalia |
| Domain archaea | Prokaryotes, ancient, extremophiles (holophiles, thermophiles, methanogens) |
| Domain bacteria | prokaryotes, everywhere else |
| Domain eukarya | Kingdom protista, fungi, plantae, animalia |
| Prokaryotes | "before nut", mainly single-celled, some filamentous but not necessarily multicellular, no nucleus, DNA long, circular strand, nucleoid, no membrane-bound organelles, most non-motile, although a few have flagella, most decomposers, autotrophs |
| Protista | "very first", most unicellular (some multi), nucleus and membrane-bound organelles, autotrophs and heterotrophs, any eukaryote that is not a fungus plant or animal |
| Animal-like protists | "protozoa" amoeba, paramecium; heterotrophs; move with cilia or flagella or pseudopods; single-celled |
| Plant-like protists | Algae (euglena, volvox, diatoms, kelp), autotrophs, single and multicellular, no waxy cuticle, gametangia |
| Fungus-like protists | Water mold, slime mold; heterotrophs; flagellated cells; cellulose cell wall |
| Fungi | mushrooms, mold, mildew, yeast; eukaryotes; heterotrophs; almost all are multicellular except yeast; decomposers: secrete digestive enzymes on food and absorb pre-digested food back; cell wall made out of chitin |
| Plantae | multicellular, eukaryotic, autotrophs; waxy cuticle; multicellular gametangia |
| Animalia | multicellular, eukaryotic, heterotrophs; ingestion then digestion internally, glycogen |
| Linnaeus 2 kingdom | Planta and Animalia |
| Woesse 3 domain | Domain archae, kingom archaebacteria; domain bacteria, kingdom eubacteria; domain eukarya, kingdom protista, fungi, plantae, animalia |
