We stain cells in different ways for different reasons. First of all, many cells and their parts are transparent and so don't show up under the microscope unless we stain them. Secondly, many stains react with the cells in different biochemical ways and this helps us to identify some organisms, for example, the Gram stain colors some bacteria purple and others pink.
What else can I help you with?
Can DAPI stain be used to visualize live cells?
No, DAPI stain cannot be used to visualize live cells as it requires fixation and permeabilization of the cells.
What do in need for viewing sperm cells?
To view sperm cells, you will need a microscope with at least 400x magnification, a glass slide, coverslip, and a stain to make the cells more visible. Additionally, you will need a sample of semen to put on the slide for examination.
Which stain you should use to stain onion peel?
To stain onion peel cells, you should use a stain called iodine. Iodine is commonly used to stain cells because it binds to starches and glycogen in the cells, making the cells more visible under a microscope.
Why do all cells stain purple in the flagella stain but not in the gram stain?
In the flagella stain, all cells appear purple due to the basic dyes used to stain the flagella. This uniform coloration helps visualize the flagella structure under the microscope. In contrast, the Gram stain uses a series of dyes to differentiate between Gram-positive (purple) and Gram-negative (pink) cells based on their cell wall composition.
Does Hoechst stain dead cells in a biological sample?
Yes, Hoechst stain can be used to stain dead cells in a biological sample. It is commonly used in fluorescence microscopy to distinguish between live and dead cells based on differences in their nuclear morphology.
Do epidermal cells from petunia stain with phloroglucinol?
No, epidermal cells from petunia do not stain with phloroglucinol. Phloroglucinol is typically used to stain lignin in plant tissues, not epidermal cells. The stain mainly reacts with lignin, which is absent in the epidermal cells.
What stain is used to stain cheek cells?

What is the stain blue used to stain animal cells?
Methylene blue is used for many different staining purposes, but one of the main ones is staining RNA or DNA. In animal cells, it will stain the cytoplasm and the nucleus (the nucleus will be much darker).
Stain name used for onion cells?
safranine stain is used to stain onion cells
Identify a stain that would be appropriate for improving definition of the blood cells?
Wright's stain is a commonly used stain in hematology that improves the definition of blood cells, particularly white blood cells. It consists of a combination of acidic and basic dyes, allowing for better visualization and differentiation of various blood cell types.
Why did early investigators predict that there must be a reduction division in the sexual reproduction process?
Early investigators predicted a reduction division in sexual reproduction because they observed that the number of chromosomes in sex cells was half that of somatic cells. They hypothesized that this reduction division ensured that when sex cells combine during fertilization, the resulting offspring would have the correct number of chromosomes.
What do you do after you enter the investigators house on poptropica?
