    cell theory
  23. What are 4 organelles ALL cells have?
    Cell membrane, DNA, ribosomes, cytoplasm
  24. Very small cells without a nucleus and membrane-bound organelles.
  25. Larger cells with a nucleus and membrane bound organelles.
  26. What is the only example of a prokaryote?
  27. Microscope that uses light and two separate lenses to magnify a very thing image. Can magnify up to 2000x (our only go up to 400x).
    Compound light microscope
  28. Microscope that uses light and binocular lenses (2 eyepieces) to magnify a larger object. Can magnify up to 50x
    Stereomicroscope (dissecting microscope)
  29. Image in inverted (upside down and backwards) when using this microscope
    Compound light microscope.
  30. How is total magnification determined?
    ocular lens x objective lens
  31. If the ocular lens is 10x and the objective lens is on 4x, what is the total magnification?
  32. Area seen when looking through the microscope
    Field of view
  33. What happens to the field of view as you switch to a higher power?
    gets smaller
  34. On which power is you image smallest but field of view largest?
    scanning power
  35. Microscope that uses electrons to show the surface of an object (magnifies up to 100,000x)
    Scanning electron microscope
  36. Microscope that shoots electrons through a thin object so you can see the inside (magnifies up to 200,000x)
    Transmission electron microscope
  37. What si a problem with using the electron microscope?
    Specimen must be dead.
  38. Larger knob on the side of the microscope that can only be used with scanning and low powers.
    Coarse adjustment knob
  39. Smaller knob on the side of the microscope that is used mostly on high power.
    Fine adjustment knob.
  40. Controls the amount of light shining on an object.
    Iris diaphragm.
  41. Eyepiece (10x) lens you look through.
    Ocular lens
  42. Where the objective lenses are attached. Rotates to change objective lenses.
    Revolving nosepiece.
  43. Where your bottom hand should be when carrying a microscope.
  44. The part your other hand should hold while carrying a microscope (not the base)
  45. 3-4 lenses with different magnifications that can be changed to see more or less of your specimen.
    Objective lenses
  46. Where the specimen/slide is places for viewing.
  47. Put the following organisms in order from more primitive to more recent: aerobic prokaryotes, anaerobic prokaryotes, eukaryotes
    anaerobic prokaryotes, aerobic prokaryotes, eukaryotes
  48. Theory that eukaryotic celsl formed from smaller prokaryotes moving inside the larger prokaryotes and they formed a beneficial relationship with one another.
    Endosymbiotic Theory

  51. With oxygen.
  52. Image Upload 18
    Is the picture an animal or plant cell and how do you know?
    Plant cell because it has a cell wall, chloroplasts, and large central vacuole.
