I know that electron microscopes kill cells and require chemical fixation but show a 3d image I know there is one type of electron microscope can see living cells

What kind of microscope is used to view living specimens?
a TEM (transmission Electron Microscope) shoots electrons through the specimen and shows internal features of the cella SEM (scanning electron microscope) Electrons bounce off of the surface of the specimen, and show a 3d image of the surface on the specimen.a STEM (scanning tunneling electron microscope) uses a needle like probe shoots electrons from the inside out, shows 3D surface image CAN be used on living specimens
The magnification and resolution capabilities are highest in the?
The Scanning Electron Microscope (SEM) has the highest magnification and resolution of all microscopes.
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.
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.
Why the light microscope also called the compound microscope?
There are more than one type of light microscopes as well as other types of microscopes such as the SEM. The first microscopes were (and still being used) are the simple light microscopes. The compound microscope has that name because it contains two types of lenses that function to magnify an object. A simple microscope is a microscope that uses only one lens for magnification. It is the original design of the light microscope. Van Leeuwenhoek’s research used this type.
Which 2 types of microscopes view objects that have been sliced and treated to improve contrast?
Binocular Dissecting Microscope and SEM
How do electrons microscopes differ TEM vs. SEM?
TEM gives 2D images and SEM gives 3D images.
What are two types of electron microscopes?
Two types of electron microscopes are the scanning electron microscope, or SEM, and transmission electron microscope, or TEM.
Are Scanning microscopes used to observe individual atoms?
No. Scanning Electron Microscopes (SEM) use electrons to view microsopic details down to the granular structure of material. Since it uses electrons, it could not detail anything the size of an Atom.
What disadvantages do SEM microscopes have of light?
The two main advantages of SEM over light microscopy is that the SEM has a much deeper depth of field and that it has higher resolution than a light microscope can achieve and the resultant much higher magnification from the SEM.

What are the types of microscopes uses and advatanges?
Compound ,Dissection or Stereoscope, Confocal Microscope, Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM).
What are the two types of electron microscopes?
Biologists use two main types of electron microscopes. Transmission electron microscopes (TEMs) shine a beam of electrons through a thin specimen. Scanning electron microscopes (SEMs) scan a narrow beam of electrons back and forth across the surface of a specimen.
How does the image you see in a SEM differ from a light microscope?
Scanning Electron Microscopes have a much larger zoom range. therefore the image from a SEM is more in depth. think of it as looking at a basketball from far away... you see an orange ball. but when you look at it upclose, you see the black lines and dimples on the ball. same goes for whatever your looking at under the SEM
What are the differences and similarities between light TEM and SEM microscopes?
a TEM microscope privides an detailed image of the inside of a specimen a SEM microscope provides a 3D image of a specimen take for exampel a sperm in a TEM microscope you would see the inner stucture of the sperm in a SEM microscope you would se in detail the exact form shape of the sperm
