7 Kingdoms & Bacteria & Viruses

6 Kingdoms

Objective 4.01:Similarities & differences among the kingdoms

1. ArchaebacteriaAncient bacteriaProkaryotic Cell (Very Simple!)UnicellularBoth autotrophs & heterotrophsHas a Cell wall that lacks peptidoglycanReproduce asexuallySome are motile (can move)Live in extreme environments (Hot, Salty, Acidic)Volcanic hot springs, Salt marshes

2. Eubacteria KingdomRecent bacteriaProkaryotic CellUnicellularBoth autotrophic & heterotrophicReproduce asexuallySome are motileCell wall has peptidoglycan (thick!)Found nearly everywhere

Organisms that cannot be classified as an Animal, Plant, or Fungi.Least satisfying of the classifications because members display the greatest variety.3 ClassificationsAnimal-like Protists: Amoeba, ParameciumPlant-like Protists: Unicellular & Multicellular; AlgaeFungi-like Protists: Slime molds & Water molds3. Protista Kingdom3. Protista KingdomEukaryoticMost are unicellular, some are multicellularAutotrophs & heterotrophsReproduce sexually & asexuallySome are motileSome have a cell wall (plant-like)

4. Fungi KingdomEukaryoticMost are multicellular (mushrooms), although some are unicellular (yeast)Heterotrophic: Absorb their food from environment.Feed on dead/decaying organic matterSecrete digestive enzymes into their food source. Absorb the food molecules through their body.Have a cell wall (chitin)Reproduce sexually & asexuallyNon-motile

EukaryoticMulticellularPhotosynthetic AutotrophsHave a cell wall (cellulose)Reproduce sexually & asexuallyNon-motileIncludes: Cone-bearing and flowering plants, mosses, & ferns. 5. Plant Kingdom

6. Animal KingdomEukaryoticMulticellularHeterotrophsReproduce sexuallyNo cell wallsMotile, except sponges.Very diverse
