   Electron Microscopy (TEM) or can look at the outer surface of a sample using Scanning Electron Microscopy (SEM), analogous to a stereo light microscope. 7.1.2 Transmission electron microscopy (TEM) The greater resolving power of electron microscopes derives from the wave properties of electrons.

   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 is transmission electron microscopy (TEM)?

   • Provided by the Springer Nature SharedIt content-sharing initiative In transmission electron microscopy (TEM), electrons are transmitted through a plastic-embedded specimen, and an image is formed. TEM enables the resolution and visualization of detail not apparent via light microscopy, even when combined with immunohistochemical analysis.

   What is the limit of resolution in a TEM microscope?

   • The practical limit of resolution in the TEM is 3–5A or 10–15A when observing cellular structures. Electron microscopes consist of a vacuum column through which the electrons travel. A cathode (like the metal wire in a light bulb) will be heated and provides the source of electrons. Focusing of the beam is by electromagnetic lenses.

   What is the limit of resolution of a transmission electron microscope?

   • The limit of resolution of the transmission electron microscope is now less than 1 nm. The TEM has revealed structures in cells that are not visible with the light microscope. Learn about and revise cell structures with BBC Bitesize for GCSE Biology, OCR Gateway.

   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.
