The TEM has revealed structures in cells that are not visible with the light microscope. SEMs are often used at lower magnifications (up to ×30,000). The limit of resolution of a SEM is lower...
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.
The basic subcellular structures of an eukaryotic cell as seen by transmission electron microscopy (TEM). Try to identify the cell borders and nuclei. Switch between the grayscale and color images (see above) to help identify the following structures: Plasma Membranes (dark green) - portions visible in cells 1, 2 and 4
Transmission electron microscope image of a human leukocyte (also known as a white blood cell), showing the Golgi apparatus, which is a structure involved in protein transport in the cytoplasm of the cell.

Unlike the transverse section thru the middle of a nucleus seen in EM 007 Nucleus, this is a tangential section thru the edge of a nucleus as seen by transmission electron microscopy (TEM). The surface of most nuclei are slightly irregular with invaginations.
