This image shows the a 2D image of the parts of a cell at 200,000x normal size. Which microscope most likely took this image?
Which microscope is useful for studying details of objects that are already visible?
Which microscope would be used to help generate a 3D model of the spike proteins on a virus, which must be magnified at least 50,000x normal size?
Dissecting
Compound
Scanning Electron
Transmission Electron
Which of these is a drawback to the usefulness of electron microscopes?
They are very inexpensive
They cannot be used to look at a living specimen
They must be used in a dark room because of their requirement for light
They can only magnify objects 100x or less
Why do electron microscopes such as SEMs and TEMs produce images only in grayscale and not in color?
X-rays are used to produce the image
Visible light is not used to produce the image
Visible light cannot travel in a vacuum
Electron microscopes that produce color images are too expensive
