One limitation of an SEM is that it can't observe living things while still alive. Biological samples must be coated in gold before observation.
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.
Light microscope cannot be used. An electron microscope houl b used
No, they cannot due to the fact that the electron microscope does not use light rays to illuminate the object; therefore, colors cannot be see since they are a reflection of light.
1. electron microscope could magnify until 200,000 and have high resolution 2. they cannot be used on living organisms because it enters a vacuum so electron don't bounce off a gas molecule 3. it allow you to view molecule 4. electron microscope is a beam that hits a specimen and hitting back to draw the molecule in the fluorescent screen this is called transmission electron microscope 5. there is a scanning electron microscope that scans specimen coated by a thin layer of metal ions that bounce back forming 3-D image
No, you cannot see individual atoms of elements with a school microscope. Atoms are much smaller than the wavelength of visible light, so they cannot be resolved by optical microscopes. Specialized techniques such as scanning electron microscopy or atomic force microscopy are needed to visualize atoms.

because an electron microscope has a vaccum chamber which cannot allow oxygen to pass
An EM is basically of 2 types. Scanning Electron Microscope and Transmission Electron Microscope. Yes definitely it is used to magnify and resolve specimens but a living specimen cannot be used. Only dead are used. This is due to certain disadvantages that come along with this microscope. If need further details over the microscope uses and types then let me know.yea...i completely agree wif yuh... :)
Yes, an electron microscope cannot operate without a source of electrical power.

You cannot see down to the nanometer scale with light microscopes, you have to use something like a scanning tunneling microscope or an electron emission microscope. And since those don't use light I'm not sure you can really define the magnification.
As viruses cannot be seen with the optical microscope, electron microscopes are used. All the "lenses" in an electron microscope are magnetic fields produced by electromagnets and/or electrostatic fields produced by electrically charged metal plates and/or rings.
A tunneling electron microscope cannot image live specimens.
No, you cannot see individual nucleotides through a microscope.With an electron microscope, it is just possible to make out some very large molecules (macromolecules), such as individual strands of DNA. But the resolution (resolving power) of even an electron microscope cannot distinguish free (uncombined) nucleotides.
