Transcript of Cell theory/prokaryotic and eukaryotic

  • 1. Introduction to Cells
    p. 67 in INB
  • 2. Cell Theory
    Cells are the foundation of all life and arise from other cells.
    Inside all cells are active structures called organelles.
    The activities that occur inside cells are called cellular processes.
  • 3. List three similarities and three differences between prokaryotic and eukaryotic cells
  • 4. Similarities between Prokaryotic and Eukaryotic cells
    Both have
    DNA
    a plasma membrane
    cytoplasm
    ribosomes
    Both may have
    cell walls
    Flagella/cilia
  • 5. Create a T-chart Differences between prokaryotic and Eukaryotic Cells.
    Prokaryotic CellsEukaryotic Cells
  • 6. Prokaryotic Cells
    Small and simple
  • 7. Eukaryotic Cells
    Larger and more complex
  • 8. Prokaryotic Cells
    Have no true nucleus
  • 9. Eukaryotic Cells
    Have a true nucleus
  • 10. Prokaryotic Cells
    Have only a single naked strand of circular DNA
  • 11. Eukaryotic Cells
    Have many strands of DNA enclosed in a membrane-bound nucleus
  • 12. Prokaryotic Cells
    Rod (oval) -shaped
    Spiral-shaped
    Round-shaped
    Are found in bacteria
  • 13. Eukaryotic Cells
    Protist cell
    Plant cells
    Animal cells
    Are found in animals, plants, fungi, and protists.
  • 14. Ticket Out the Door
    What is wrong with this statement?
    Prokaryotic cells arise from air and water. They are more complex versions of eukaryotic cells since they have a nucleus with circular DNA and include all bacteria and fungi.
