Why are cells stained or dyed before watching in the light microscope?

To better visualize cells and cell components under a microscope. stains can differentiate colors. For example, blue stains can go deep into very dense molecules, whereas red stain can not go into them.The iodine is use to kill the cell, so the cell will not move .

A well stained leaf peel mount when observed under the high power of a microscope shows nuclei in?
guard cells,epidrmal cells and stoma
What colour are cheek cells?
methelyn blue
What cell structures can be seen in a stain onion cell?
The structure that is seen is the cell wall. This keeps the shape of the cell and is only found in plant cells. The organelles that can be see in a stained onion cells all depends on your microscope. Under a x400 light microscope we could see the cell wall, cell membrane, nucleus and cytoplasm,
Why do you use the onion for cell sample and not the leaf?
An onion is easy to peel to 1 layer of cells, and with a light microscope you cant see the individual cells in a leaf. Also the cell obtained from the bulb of onion is colorless, hence it can be easly stained with different dyes to study the cell organells under the microscope.
What problems did scientists have before the invention of the microscope?
Before the invention of the microscope, nobody knew that the microscopic world existed. As a result nobody knew what they were missing out on, and so there were no known difficulties to not having microscopes.
Why are cells stained or dyed before being looked at with a light microscope?
because the dye goes into the cracks of the cells and makes it easier to see each individual one.

Why are bacterial blood cells stained before examination?
transparent
Why do you think little was known about cells before the invention of the microscope?
Because cells were difficult to see without a microscope.
What colour are cheek cells?
methelyn blue
Why couldn't people see cells before the 1500s?
Because cells are so tiny you need a microscope to see them, and the microscope was invented in 1590, therefore you could not see cells before then
Why did the microscope have to be invented before cells could be discovered?
Because if the microscope wasn't invented we would have no clue that cells existed.
How are tzanck preparations done?
is done by smearing cells taken from a fresh blister or ulcer onto a microscope slide. The cells are stained with a special stain, such as Wright's stain, and then examined under a microscope for characteristic changes caused by a herpes virus
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.
How do you examine leaf epidermal cell?
Leaf epidermal cells are examined by making peelings of epidermal cells from both sides. Normally these peelings are stained and examined under the compound microscope.
Do cells have a dark round spot in them?
Cells can be stained in laboratory setting for contrast and better visibility under a microscope. One type of staining is called a gram stain. The cells take up the dying agent(s) in varying degrees, and often times, the nucleus of the cell stains darker than other cellular components. When viewing the stained cells under a microscope, it is possible to identify the cells nucleus by the presence of an elliptical, oval, or elongated darkened spot.
