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
What is the principle of crystal violet staining in monolayer culture?
Crystal violet staining in monolayer cultures involves fixing the cells to the culture dish surface, staining them with crystal violet dye, which binds to negatively charged molecules in the cells, and then washing away any unbound dye. The stained cells can then be visualized under a microscope for quantitative analysis of cell density or morphology.
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.
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.
What structures of the cells were stained the darkest?
In a cell stained sample, structures with higher nucleic acid content, such as the nucleus and nucleoli, tend to stain the darkest due to the affinity of dyes like hematoxylin to bind to DNA and RNA. Published images of stained cells often show the nucleus as the darkest stained structure under light microscopy.

What substance is stained by Sudan dye?
Sudan dye stains lipids or fats. It is commonly used in laboratory settings to help visualize and detect the presence of lipids in cells or tissues.
Use of trypan blue in cell counting?
u count dead cells stained by trypan blue. trypan blue enters the cells only when it has died since when a cell dies it looses its property of controlling selective inlet of micromolecules. When cells r alive it doesn't allow inlet of trypan blue so viable cells r not stained. viable cells = total cells - trypan blues stained cells Nitin Ghoshal Dept of Biotechnology NEHU, Shillong, Meghalaya, India
What colour are cheek cells?
methelyn blue
How does nigrosin stain work?
Nigrosin stain is an acidic, anionic dye that works by staining the background of a sample, allowing for better contrast with the stained structures. It is commonly used in microbiology for negative staining techniques to highlight the morphology and arrangement of bacterial cells. The dye is repelled by the negatively charged bacterial cell walls, resulting in a clear outline of the cells against the stained background.
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.
What is a medical term meaning easliy stained with red dye?
Eosinophilic
What is a 4 letter word with Y ending with D?
Dyed as in stained with a dye

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 are differences in appearances of cytoplasm in stained cell and cytoplasm in unstained cell?
In stained cells, cytoplasm appears colored due to the binding of the dye to various cellular components, making structures like organelles and the cytoskeleton more visible under the microscope. In unstained cells, cytoplasm appears transparent or slightly opaque, making it difficult to observe specific cellular structures without staining. Staining enhances the contrast and visibility of cellular components, aiding in their identification and study.
What does the medical term eosinophilic cytoplasm mean?
The cytoplasm can be stained a pink color by the dye eosin.
