a TEM (transmission Electron Microscope) shoots electrons through the specimen and shows internal features of the cell
a 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
What else can I help you with?
Can light microscopes be used to view living samples?
Yes, they can.
What microscopes can be used to view living samples I. compound microscope II. dissecting microscope III. scanning electron microscope IV. transmission electron microscope?
I and II. Compound and dissecting microscopes can be used to view living samples due to their lower magnification and non-destructive imaging techniques. III and IV. Scanning and transmission electron microscopes are not ideal for viewing living samples as they typically require a vacuum environment and can damage the specimens.
Is a light microscope used to view dead a or alive samples?
A light microscope can be used to view both dead and alive samples. It allows for high magnification and resolution of biological samples, making it a versatile tool for studying a wide range of materials.
A bright field microscope can be used to view?
A bright field microscope can be used to view stained samples that absorb light, making them appear darker against a bright background. It is commonly used in biology labs to view cells, bacteria, and tissue samples.
What can you view with a dissecting scope microscope?
A dissecting microscope is typically used to view larger, three-dimensional samples such as insects, plants, or circuit boards with lower magnification. It provides a stereoscopic view and allows for manipulation and dissection of samples due to its larger working distance and field of view.
What type of microscope do you use to view living organisms?
A compound light microscope is commonly used to view living organisms. This type of microscope uses light to illuminate the sample and allows for observation of live specimens in real time. Additionally, phase contrast microscopy or differential interference contrast microscopy can be used to enhance details in transparent or unstained samples.
Does a light microscope used to view live or dead samples or its range of magnification?
A light microscope can be used to view both live and dead samples. The range of magnification for a light microscope typically falls between 40x to 1000x, depending on the specific lens and microscope configuration.
Why electrons microscopes cannot be used to view the structure of living cells?
Spicemen must be placed in a vacuum chamber. Since living cells cannot survive in a vacuum, they cannot be viewed using elctron microscopes.
What can be used to be used to view living organisms?
A compound light microscope.
Where can one view cool business card samples?
"Any company that makes business cards, cool or square, will have samples for you to look at. You can view these on their websites or at the stores in person."
What websites let me view paint samples?
You could find and view paint samples on Behr's website: http://www.behr.com They have a lot of paint color ideas on their website that you might find helpful.
Why clinical trials can't be done on human tissues?
The tissue samples are not alive. They are not living or moving like a living human. The effects of the drugs may be different on 'non living' samples may be different to the effects on a non-living human.
