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
I think both the techniques can be used to observe different organelles in a cell.Transverse electron microscope is relatively cheaper but does not produce high quality images of the sample. On the other hand, scanning electron microscope cost a lot but gives high quality images and is also more detailed.
Up to about 750,000 times. Strictly, it is not magnification that matters with any microscope. There is no practical value in enlarging an image if the enlargement reveals no further detail, but just makes the blur bigger!The critical factor is resolution, which is a measure of the detail that can be discerned in the image. A transmission electron microscope (TEM) has, at best, a resolution of about 1 nm, which means that objects closer than 1 nanometer apart cannot be distinguished. This is about 100 times the best resolution available using a light microscope.
It is not possible to see organelles with a compound light microscope because some organelles are to small to be seen with the low magnification of the light microscope. If they can not be seen through the compound microscope they are normally looked at through the electron microscopes (transmission electron microscope {TEM} or scanning electron microscope {SEM}).
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.
optical microscope and TEM
The process used to produce TEM will cut cells and tissues in to ultra-thin slices so that they can be viewed under the microscope. However, the ones on SEM do not need to be cut as they can easily be visualized.
light microscope or SEM or TEM electron microscopy
Transmission Electron Microscope is used to take an image of a cell and split it and get information from the inside of the cell
A transmission electron microscope, known as TEM, refers to a form of electron microscope wherein an image is derived from electrons that have passed through the specimen. It is used to study objects at the atomic level.

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
Its an electron microscope.It might be scanning electron microscope or TEM
SEM, which stands for Scanning Electron Microscope produces images by penetrating the specimen with a fixated beam. This beam is used to scan a rectangular portion of the specimen. Images are reliant on surface processes and they are incomplete, unlike TEM images. TEM, which stands for Transmission Electron Microscope utilizes an electron emission of high voltage. They produce complete images.
