   What cytoplasm is visible on a TEM micrograph?

   • Figure 01-08: TEM micrograph showing a 70,000× magnified portion of the cytoplasm of a plant cell. The ER, a Golgi stack, and some vesicles are visible. The structures are near the edge of the cell, as a cell wall is visible on the right-hand side of the image.

   What is a TEM cytoplasm?

   • Similarly, TEM allows for much higher magnification images, so if you’re seeing only a small subsection of the cell’s cytoplasm in great detail, it’s probably TEM. If you can see a whole cell, or even a large part of a cell, it could be either TEM or brightfield, so here you need to think about resolution.

   What can we see in a cell with a light microscope?

   • We also can see some of the larger subcellular organelles in a cell (like the nucleus and mitochondria), but not much of the smaller organelles. Also, any structure that we can see that’s close to the limit of resolution of the light microscope won’t have much detail visible.

   What is transmission electron microscopy (TEM)?

   • In Transmission Electron Microscopy (TEM), we detect electrons that have interacted with atoms in the sample as they passed through it, producing a “ projection ” image of the 3D object onto a 2D plane, similar to a medical X-ray image. This shows details throughout the cell, not just on the surface.

   What is a TEM microscope used for?

   • The TEM can also be used to study the surface of a specimen—and generally at a higher resolution than in the SEM—in such a way that individual macromolecules can be seen. As in scanning electron microscopy, a thin film of a heavy metal such as platinum is evaporated onto the dried specimen.
