HOW CAN I TELL IF A CELL HAS DEPTH BY USING A MICROSCOPE??

  • science -

    When you observe a cell under a microscope, especially at higher
    magnification, the fact that you have to focus up and down through the cell
    to see different parts of it is an indicator that the cell has a certain
    thickness. On some microscopes, the fine focus is calibrated in microns
    (millionths of a meter) so you can actually measure the approximate
    thickness of a cell by how far you turn the fine focus knob to focus from
    one side of the cell to the other. In general, cells are about 10 to 20
    microns in thickness but this can vary quite a bit depending on the cell
    type and how it was prepared. Some more sophistacated microscopes like
    Laser Scanning Confocal Microscope or a Scanning Electron Microscope allow
    you to take more accurate measurements of cell thickness but a simple
    student microscope can give you a pretty good estimate.
