A Confocal Scanning Microscope ________

Question

A confocal scanning microscope ________.
A)uses visible light to form a specimen image
B)shows three-dimensional cell images from the cell surface to the middle of the cell
C)produces specimen images on electron micrographs
D)uses dyes that emit visible light when bombarded by electrons
E)requires specimens to be stained

Accepted Answer

A confocal scanning microscope uses lasers to create a three-dimensional image of a specimen, focusing only on a thin layer at a time. This allows for images to be captured from the cell surface all the way through the middle of the cell. It does not use visible light or electron micrographs, and while staining is often used to enhance the image, it is not always required.
