  6. Cell Theory
    • 1. All living things are made up of cells
    • 2. Cells are the basic unit of structure & function ¬†(Basic Unit of Life)
    • 3. Cells come from pre-existing cells (Cell Division)
  7. Endosymbiotic Theory
    Lynn Margulis; organelles were at one time their own cells

    • -no nucleus
    • -DNA= free floating
    • -tiny-cell wall and cell membrane
    • -flagella
    • -tail that allows cell to move
    • -no membrane-bound organelles
  10. Eukaryotic
    • nucleus¬†
    • DNA= in nucleus
    • larger
    • no flagella
    • plant/animal cells
    • membrane-bound organelles
  11. Components
    • 1. Cell membrane- outside of cell (plasma membrane)
    • 2. Nucleus(DNA)- cell's genetic material
    • 3. Cytoplasm- between nucleus and cell membrane (cytosol)
  12. Animal Cell
    • Circular
    • Cell membrane
    • Small vacuole
  13. Plant Cell
