Verified step by step guidance1
Understand the different types of microscopy: Light microscopy uses visible light to illuminate specimens, while electron microscopy uses electrons.
Identify the two main types of electron microscopy: Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM).
Learn the principle of Transmission Electron Microscopy (TEM): It works by transmitting a beam of electrons through a very thin specimen, allowing for the observation of internal structures.
Contrast this with Scanning Electron Microscopy (SEM): SEM scans the surface of a specimen with a focused beam of electrons, providing detailed surface images.
Recognize that FRAP (Fluorescence Recovery After Photobleaching) is a technique used in fluorescence microscopy, not electron microscopy, and involves observing the movement of fluorescent molecules within cells.
