Why can tooth and gum bacterium be seen with negative staining?
Not all oral bacteria are gram negative, but those that are there can be seen with Gram stain.
Did you stain the bacterial cell wall or the cell cytoplasm?
Yes, it is. Using the Gram staining method, the wall can be seen.
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.
What are the names of special stains in microbiology?
In microbiology the concept of staining is very important because it highlights the structures of microorganisms allowing them to be seen under a microscope (because ordinarily the microorganisms are somewhat transparent making them difficult to see). In the case of some bacteria, many have specific surface structures such as capsules and flagella as well as internal components such as endospores. To specifically enhance these structures, a special stain may be used. An example of this is using negative staining techniques to see capsules, or using the Ziehl-Neelsen technique to see endospores.
Why do biologists use different stains?
A lot of tissue is the same colour and density: have you ever look at glass under water, it is much the same thing. Staining things makes different things take on colour and they can be seen much more clearly. I believe the first medical staining was done by Doctor Erhlich in working with the tuberculosis bacterium.
Why can tooth and gum bacterium be seen with negative staining?
Not all oral bacteria are gram negative, but those that are there can be seen with Gram stain.
What are gram negative diplocci?
Gram negative diplocci is the name given to describe the structure and shape of the bacteria, Neisseria gonorrhoeae (the infective organism of the STD gonorrhea) as it is seen on the microscope using a technique call gram staining.
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.
Did you stain the bacterial cell wall or the cell cytoplasm?
Yes, it is. Using the Gram staining method, the wall can be seen.
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.
What are negative ways to get power?
bullying can be a way to be seen and heard
Are rainbows invisible?
If you have ever seen one, then the obvious answer is negative.
What is negative space?
Negative space is the space where something can be seen that was not necessarily created. These are added effects in paintings for example.
What characteristics does a normal kidney biopsy have?
The results are normal if no abnormalities can be seen in the tissue samples with the naked eye, with an electron microscope or through staining with a fluorescent dye (immunofluorescence).
What is the reason for staining the Elodea cells with Navashin's solution?
The tissue is structurally unaltered by the treatment process, and yet itbecomes uniformly translucent so the organelles can be seen easily.
What is a word that begins with a q in genetics?
Q-banding: The pattern of bright and dim fluorescent crossbands seen on chromosomes under ultraviolet light after quinacrine mustard staining.
What is the purpose of staining a specimen?
The reason for staining specimens is to see certain organelles within a eukaryotic cell. These structures as well as the cell itself are normally translucent. The stain provides a contrast that will make the part one wants to see more visible. With prokaryotic cells, staining helps identify the type of bacteria. Staining also allows us to see parts of the cell that would normally be unidentifiable by the biologist. I am sure that you have seen pictures of cells in mitosis or meiosis where the chromosomes have been stained and are readily apparent.
