5 True/False questions
transmission electron microscope → an electron beam scans the surface of the sample. The beam excites electrons on the surface and these secondary electrons are detected. The result is the image
cell fractionation → takes cells apart and separates the major organelles and other sub cellular structures from one another.
rough er → surface lacks ribosomes
nucleolus → region that is not membrane enclosed
nucleoid → a prominent structure within the nondividing nucleus which appears through the electron microscope as a mass of densely stained granules of fibers adjoining part of the chromatin.
