    A eukaryote that is not a plant, fungus, and an animal
  6. A monophyletic group is a common ancestor and all its descendants and an example are
    Eukaryotes
  7. What is not a monophyletic group
    Protista (polyphyletic)
  8. How are animals unique
    have a nervous system
  9. prokaryote engulfing a aerobic prokaryote
    serial endosymbiotic theory
  10. Not united by any unique features, or shared, derived traits
    Kingdom Protista
  11. First membrane bound organelle
    Mitochondria
  12. Life cycle very complex
    Kingdom Protista
  13. Animal Like Protists are similar to
    Plant like protists
  14. Eukaryotic cells contain
    Membrane enclosed nucleus, Endomembrane System, Mitochondria for respiration, Cytoskeleton, Flagella, life cycles that include mitosis meosis and sex, multiple chromosomes
  15. No body axis, Asymmetrical body plan, No plane of symmetry
    animal - like protist
  16. single celled protists increase surgace area by
    flattening their bodies
  17. Hypotonic solution
    more water is coming into the cell
  18. Hypertonic solution
    more water is coming out of the cell (salty)
  19. isotonic
    equal amounts of water are coming in and our of the cell, marine enviroment
