Although Transmission Electron Microscopy Is Usually Used for High-Magnification Viewing

question 69

Multiple Choice

Although transmission electron microscopy is usually used for high-magnification viewing, it is certainly possible to use it at low magnification as well. That is, one can produce similar micrographs of tissues taken by light microscopy and electron microscopy at the same magnification. Even at the same magnification, however, you can easily tell the two kinds of micrographs apart. How?

• A) Tissue for electron microscopy cannot be sectioned.
• B) The image in the electron micrograph is still sharper.
• C) Tissue for light microscopy cannot be fixed (no fixation).
• D) Tissue viewed by electron microscopy is colored, whereas light micrographs are always black and white (and shades of gray).
