Explain how to prepare a specimen for viewing in a electron microscope?

For a scanning electron microscope, the most commonly used type of EM, there is no need to do anything other than stick it to an electrically conducting pad. If the sample is particularly insulating, it may be worth coating it with a very thin gold layer to prevent the specimen from charging up with electrons from the beam (this would blur the image)
For a transmission electron microscope, the specimen is most commonly encased in epoxy resin before being sliced into thin enough slices that the electron beam can pass through. The sample is then placed on a fine copper grid before being placed in the microscope.

Why can't you view living cells through electron microscope?
"In electron microscope the object is viewed in highly vaccum conditions. Living cells would disentegrate in such a condition." This answer is not mine it comes from the "why can't electron microscopes be used to view cell structures" question
Can you prepare microscope slides for cell division?
Yes, you can.
A student wants to prepare a temporary mount of spirogyra Where should he search for a fresh specimen?
In a pound of a salty water
How do you prepare a wet mount slide for the microscope?
Take a clean slide (either depressed or flat) and add a drop of water using an eye dropper. Add the specimen and using the slip cover, touch the end of the slip cover to the water. Lay flat as smoothly as possible to omit bubbles from forming.
Why do you need a drop of water to prepare slides when using microscope?
Because an air bubble, trapped between the slide and cover plate, shows as a dark'blob' under magnification. Using a drop of water to 'seal' the slide & cover plate together excludes the air - making the specimen more visible to the user.
How must samples be prepare for observation by electron microscope?
They must be preserved and dehydrated. Once this is accomplished, put the specimen onto a slide, and then the slide is ready to be viewed under the microscope.
What are the Kinds of microscopes and their uses?
There there are many. Simple microscope, compound microscope, light microscope, scanning electron microscope, TEMicroscope, Dissection microscope, etc and most of them are used to see small cells that cannot be seen by the naked eye.

Is varicella zoster virus gram negative of gram positive?
Gram-positive and gram-negative refer to the Gram stain used to prepare slides of bacteria for viewing under a light microscope. Viruses are too small to see under a light microscope and have to be prepared differently for viewing under an electron microscope. So the answer to your question is neither
Why glycerin is used to prepare a temporary mount?
Glycerine is quite isotonic to the cell. So, it does not damage the specimen.
Which statement describes the best way to prepare a microscope for safe transport back to a storage area?
Wrap the electrical cord around the arm of the microscope.
