What is the main purpose of a Transmission Electron Microscope (TEM)?
To study the internal ultrastructure of cells
How is the image in a Transmission Electron Microscope (TEM) enhanced?
By staining the thin section of preserved cells with atoms of heavy metals
What is the main difference between a Transmission Electron Microscope (TEM) and a Scanning Electron Microscope (SEM)?
TEM studies the surface structure, while SEM studies the internal ultrastructure of cells
How does a Scanning Electron Microscope (SEM) produce its images?
By collecting and focusing secondary electrons from the sample surface
Learn about the differences between Transmission Electron Microscope (TEM) and Scanning Electron Microscope (SEM) and their applications in studying cell structures. Understand how TEM is used to study internal ultrastructure of cells through thin sections, while SEM is used to study surface structure of cells with a thin film of gold.
