Can cells be stained with dye?
Live staining is possible as is the preparation of fixed tissue.
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.
Who cannot see close objects clearly are?
Far-sighted people cannot clearly see nearby objects.
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.
Which of the following clues would you tell if a cell is prokaryotic or eukaryotic?
First of all, by size. Prokaryots are bacteria and they are generally a lot smaller than eukaryotes. With most light microscopes, you can see a human cell quite clearly, and you can clearly distinguish the nucleus and in the nucleus you can distinguish euchromatin and heterochromatin. A bacterium on the other hand just looks like a dot. Its too small to try and see any interior structures through an average light microscope.Apart from that, in a eukaryotic cell in mitosis, if the nucleus is no longer present, the chromosomes are still clearly visible in the cytoplasm.

Why is it hard to see detail in cells and tissues?
It is difficult to see detail in cells and tissues due to their microscopic size. This problem can be alleviated with the use of microscope, although certain structures may need a very high magnification and staining to be able to make out clearly.
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.
Why do you need to stain some of the cells with a dye like iodine?
without staining the cell you would not be able to see it clearly. the cell would be transparent. methylene blue stains the whole cell properly so that you can see each cell organelle clearly.
Why are stained cells used to show a phase of the cell cycle?
Cells tend to be rather transparent under the microscope, and staining them makes it much easier to see the internal structures.
What research microscope is used to see unstained living microbes and intracellular structures?
The microscope that is used to see internal structures of cells in a natural state is the compound light microscope. The microscope has a lens and light that allows it to see the internal structures of a cell clearly.
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.
What is purple and pink in cell organelles?
What you are asking about is probably just the chemical stains added to the slide to help make things visible. Most structures in cells are just transparent and barely visible without this artificial staining. Different colored stains attach better to different cellular structures, thus helping to identify them. One of the few cellular structures that is naturally colored and thus easy to see without staining are chloroplasts, which are a bright green from the chlorophyll they contain.
How are stains used in electron microscopy?
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 .
Why is alcohol in a thermometer colored?
So that you can see it more clearly.
Why should you back towards the side?
To see more clearly.
How does the microscope help you see better?
makes it bigger and so you can see it more clearly.
