What type of microscope would a biologist use to study the protein molecules on the surface of a cell?
transmission electron 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
Types of microscope and their uses?
Compound microscopes can be found in most biology and science classrooms. They are electrically operated and use light to enhance the image of a cell. They will have multiple lenses for viewing.Dissecting microscopes are also known as stereo microscopes. They have low magnification and are also light powered. These microscopes can view objects larger than what a compound microscope is able to handle, in three dimensions.Scanning Electron Microscopes use electrons instead of light to create an image. These microscopes produce three-dimensional images with high resolution and magnification. They also have a larger depth of focus.Transmission Electron Microscopes use electrons instead of light to create an image. The material prepared must be very thin. The beams of electrons that pass through it give the viewer high magnification and resolution. These give two-dimensional images.Electron microscopes are one of the most advanced microscopes used today. This microscope is powered by a beam of electrons with very short wavelengths. These electrons strike objects that come in its path and helps increase the resolution of the microscope. The electron microscope is one of the types of microscopes used to study cells like tiny viral cells as well as larger molecules.
What type of microscope is best for studying DNA?
electron microscopes...According to my course in OK Virtual Highschool.."Hi-tech electron microscopes are used to study very small objects such as viruses. They can also be used to view the smallest of molecules that make up cells such as DNA in the nucleus. Unlike a compound microscope, an electron microscope can produce a three-dimensional image"
What type of microscopy does not use light?
Electron microscopy; Scanning Electron Microscopes (SEM) and Transmission Electron Microscopes (TEM). The vacuum required for electron microscopy to work correctly precludes the observation of living organisms. Biological samples must be dried then coated with a conductive metal.
What the microscope can not do?
Microscopes cannot view viruses as viruses are smaller than the wavelength of visible light (about 0.2 microns). To view extremely tiny objects, scientists use electron microscopes. Electron microscopes use electron beams instead of light to magnify objects less than 1nm!
Why do scientist use electrons for microscopes instead of light?
Scientists use electron microscopes rather than electron microscopes due to the cause of electron microscopes are better at looking deeper into the object you want to see.
What types of objects can be studied with a light microscopes. what types can be studied with an electron microscopes?
Light microscopes are used to study living organism and to watch and analyze their structures. Electron microscopes use a dead specimen and are able to observe structures in great detail and with much much higher magnification. +++The electron microscope has a far higher definition and magnification than an optical microscope could achieve, but as you say you could not use it to study a living organism.
What type of microscope would a biologist use to study the protein molecules on the surface of a cell?
transmission electron microscope
How does the electron microscope permit scientists to see viruses?
Viruses are very small and can be considered ultramicroscopic. We were not able to see them with the best light microscopes as we could bacteria (prokaryotes). We have to use an electron microscope to see them as they are that small. This was not available until recently.

How are light microscopes and electron microscopes different?
Light microscopes use light zo you can see close up but they are not as powerful. Electron microscopes use of coarse electrons and thats when you see the really close up of cells.

What kind of microscopes use beams of electrons to produce magnified images?
These microscopes are called electron microscopes.
What do electron microscopes use to focus and magnify image?
Electron beams.
What is the difference in the way light microscopes and electron electron microscopes produce images?
light microscopes allow light to pass through the specimen and use two lenses to form an image. Electron microscopes use beams of electrons, rather than light, to produce images.
What are microscopes used?
Microscopes are used to see things too small for the naked eye. They are used to look at cells from plants and animals and many other things that our eyes can't see. Geologists use them to study rock samples. Biologists use them to examine cells, bacteria, and the structures of bones and tissues. Doctors and forensic pathologists use them to study the changes in tissues that can cause illness or death. Manufacturing chemists use microscopes to study how chemicals interact. Engineers use microscopes, electron microscopes and x-rays to study the form and structure of materials, and how they react to physical and chemical changes.
