What colour are cheek cells?
methelyn blue
A well stained leaf peel mount when observed under the high power of a microscope shows nuclei in?
A well-stained leaf peel mount observed under high power of a microscope will show nuclei in the plant cells. Nuclei in plant cells appear as darkly stained, round or oval structures within the cytoplasm of the cell, providing important genetic and regulatory functions for the plant cell.
How can you observe a white blood cell in a light microscope?
White blood cells can be observed in a light microscope by preparing a blood smear, staining the cells with a dye like Wright's stain or Giemsa, and then viewing them under high magnification. The cells will appear as small, irregularly shaped cells with a dark-stained nucleus and a lighter-stained cytoplasm.
What can you use to observe cells going through mitosis?
You can use a light microscope with stained slides of cells to observe cells going through mitosis. Staining techniques such as using dyes like Hoechst or DAPI can make the chromosomes more visible under the microscope. Time-lapse imaging can also be used to track the progression of mitosis in real time.
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 are 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 cells stained or dyed before being looked at with a light microscope?
Cells are stained or dyed before being viewed under a light microscope to enhance their visibility by adding color to specific parts of the cell, making it easier to identify different structures. Staining can help researchers distinguish between different cell types, visualize cellular structures more clearly, and highlight specific components of interest within the cell.
Can we see cytoplasm in a light microscope?
Yes, the cytoplasm can be seen in a light microscope as it appears as a dense, granular material filling the interior of a cell. It is not visible when cells are stained properly.
What is they name of the special dye you put in cells?
There are many types of dyes available depending on what kind of cells are being stained. Plane cells can be stained with Iodine Bacteria can be stained with Gram's reagent Animal cells can be stained with Trypan Blue. They can also be stained with Hematoxilin and Eosin
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.
Can i see Sperm under microscope?
Yes, sperm cells can be seen under a microscope. They are typically stained with a dye to make them more visible. Sperm cells are very small, measuring about 5 micrometers in length, so a high-powered microscope is needed to observe them clearly.
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
