What is the purpose of staining a specimen when using the microscope?
Staining a specimen allows you to better see what exactly is under the microscope. It helps to separate the specimen and the slide underneath or on top. Another way to think of this is like is it easier to see white sprinkles on white frosting, or blue sprinkles? Blue, of course! It's just easier to see.
What is the importance of staining specimen for observation under the microscope?
Most cells contain structures that are transparent and without color, which makes visualization difficult, even with the aid of a microscope. Cell staining is used to gain more information about cells and tissues, and allows for the structures within cells to be seen in great detail
Why was koch's recommemdation for fixing and staining important for microbiology?
Koch's recommendation for fixing and staining is important for microbiology even though all bacteria can be seen under the microscope, because staining and fixing is needed in order to see inside of a transparent bacteria.
What effect did staining the onion cells have on their appearance under the microscope?
how do cells of the onion specimen appear under the microscope
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.

Function of heat-fix in gram staining?
Heat fixing is done to kill the specimen; adhere the specimen to the slide; and alter the specimen so that they more readily accept stains.
What advantage can be gained from staining cells?
they are easier to see when you use a microscope
What is a phase microscope?
A phase-contrast microscope (or phase-difference microscope or phase microscope) allows better viewing of clear specimens that usually need to be stained before you can make out the various parts. Staining is a time consuming process and kills the cells being viewed. With a phase-contrast microscope, living cells can be studied as they go through the cell division cycle.HOW IT WORKSAs light goes through a transparent specimen, there may not be anything interesting to see. However, the light undergoes phase changes as it passes through the different parts of the specimen. Unfortunately, the human eye does not notice phase changes. A phase-contrast microscope converts these unnoticed phase changes into differences in brightness, which the human eye sees very well. The darker and lighter parts of the specimen make it very visible.This also works on reflected light microscopes.
What would happen if no fixing were done?
If no heat fixing was done to a slide with a specimen on it, it would be rinsed off with the gram staining procedure. Heat fixing the specimen does kill specimen but it also locks it in place.
What effect does staining have on plant cells?
It will make them stand out more under a microscope
What is the organelle that not possible to observe without electron microscope?
Will proper staining and the right organism the nucleus of a cell can be seen without an electron microscope.
