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.
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...
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.
May 31, 2022 · Notice the lack of a cell wall. TEM electron micrograph of a plant cell showing key features. Notice the presence of a cell wall and vacuole. Mucus producing goblet cells (found in the lining of trachea, bronchi and larger bronchioles) are shown in a photomicrograph.
Figure 01-01: Examples of the four different types of microscopy, imaging green algae cells (species unknown): brightfield light microscopy, fluorescence light microscopy, transmission electron microscopy (TEM), and scanning electron microscopy (SEM). An average algal cell is between 2 and 7 µm.
The photo in (a) shows the tall cylindrical microscope, which has a binocular eyepiece near its base. The microscope stands on the bench and the images are displayed on computer screens beside it. The electron micrograph in (b) shows a roughly spherical cell with its darkly staining (electron-dense) nucleus toward the left.
