  17. When converting from a small to a larger quantity, or from a large to a smaller quantity, what do we do to the decimal place?
    • Small to Large = Move it to the Right
    • Large to Small = Move it to the Left
  18. How do you find the true magnification of a microscope?
    Multiply the magnification of the objective and ocular lenses.
  19. Magnification of Microscope Lenses
    • Objective Ocular Lens Objective Lens Total Magnification
    • Scanning
    • Power 4x 10x 40x
    • Lower
    • Power 10x 10x 100x
    • High
    • Power 40x 10x 400x
    • Oil
    • Immersion 100x 10x 1000x
  20. Animal vs. Plant cells
  21. 1) Animal cells have a plasma membrane while plant cells have a cell wall.
    • 2) Plant cells have chloroplasts to obtain energy from the sun while animal
    • cells do not.
    • 3) Plant cells are rigidly stacked together while animal cells do not have a
    • high level of organization.
  22. Isotonic
  23. Same amount of solutes inside and outside of the plasma
    membrane. The potato remains the same as before it was placed in solution.
  24. Hypotonic
  25. More solutes inside membrane, water rushes in to equilibrate
    • concentrations and the cell swells. In our case, the potato becomes very
    • rigid from higher water concentration.
  26. Hypertonic
  27. More solutes outside the membrane, water rushes out to
    • equilibrate concentrations and cell shrivels. The potato becomes very flaccid
    • and weak.
