We use stains for microscopy so we can see the microorganisms better, because most microorganisms are transparent, we cant see that well just by microscopes, so we use stains which stain the microorganism which helps you find them and look at them easier .Stain are colors which enable us to differentiate internal structures clearly .

∙ 6y agoSome objects don't show up under an electron microscope (just as some don't on an optical one)... Staining the specimen - makes it more visible.

What are the tools that scientists used to observe atoms?
They could use an electron microscope or an STM (scanning tunneling microscope)
What is the function of staining jar?
There are several uses for a staining jar. In microscopy, it is used for staining tissues and cells for slides. After being stained with dyes or stains, the specimens can also be placed in the jar to look for certain aspects.
At what total magnification should you begin to look at a sample?
Depending on what microscopy you are doing.. Bacterial microscopy starts with 40x and Blood smear microscopy at 10x.
Introduction in basic techniques in microscopy?
Introduction to basic techniques in microscopy involves light microscopy, laser scanning, types of dyes, the cell, electron microscopy, differential interface microscopy, histological stains and histochemical stains.
Which type of microscopy is used for colorless specimens?
Transmission electron microscopy
What does FESEM mean in electron microscopy?
Field Emission Scanning Electron Microscopy
What has the author Robert F Bils written?
Robert F. Bils has written: 'Electron microscopy' -- subject(s): Electron microscopy, Laboratory manuals, Microscopy, Electron
How is osmium used for microscopy fingerprint detection?
Osmium tetroxide (OsO4) is used in fingerprint detection. It is a strong oxidant and it reacts with unsaturated carbon-carbon bonds in lipids which are found in fatty tissue. It fixes biological membranes in tissue samples and also stains them. Osmium atoms have a very high electron density so such stained samples have a very high image contrast in electron microscopy.
What has the author Jan Vincents Johannessen written?
Jan Vincents Johannessen has written: 'Electron Microscopy in Human Medicine: Part A' 'Diagnostic electron microscopy' -- subject(s): Case studies, Electron microscopic Diagnosis, Electron microscopy
Does light microscopy offer better magnification than electron microscopy?
No
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 has the author Alex Ferenczy written?
Alex Ferenczy has written: 'Female reproductive system: dynamics of scan and transmission electron microscopy' -- subject(s): Atlases, Cytology, Diagnosis, Diseases, Electron microscopic Diagnosis, Female Generative organs, Female Genitalia, Microscopy, Electron, Scanning, Scanning electron microscopy, Transmission electron microscopy
Light microscopy and electron microscopy differences in practical use?
Electron microscopy gives higher resolution, but it's expensive, slow, and cumbersome. And for many things, it's not needed.
Which type of microscopy is useful for viewing colorless specimens?
Transmission electron microscopy
Simple staining is often necessary to improve contrast in what microscope?
The type of microscopy that uses chemical stains to add color and increase contrast is light. The type of microscope that can be used to observe very small surface details is called a scanning electron.
