Because most microbial cytoplasm as well as cellular cytoplasm, studying microorganisms under a light microscope is like trying to look at something white on a white piece of paper. So, scientists have to stain a cell before they can observe it. One of the most common stains is the Gram Stain.
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.

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).
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.
In a gram stain the primary stain is crystal violet. Iodine then sets that dye into the gram positive cells while alcohol washes out the crystal violet from the gram negative cells. Then safranin, which is the counterstain in a gram stain, is used to dye the rest of the bacteria. This is the example I can give you of why a counterstain does not change the look in all the cells. Though safranin stains all the cells, the gram positive cells that were dyed purple from crystal violet don't look pink - only the gram negative do.
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.

No, DAPI stain cannot be used to visualize live cells as it requires fixation and permeabilization of the cells.
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.
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.
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.
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).

A stain used to observe the organelles of cells.
Heating the onion root tip cells softens the cell walls and allows the acetocarmine stain to penetrate the cells. The stain then binds to the DNA in the cells, making the chromosomes visible under a microscope for easier observation and analysis in cell division studies.
Plant cells are typically stained with dyes like iodine to highlight structures like nuclei and starch granules. Animal cells can be stained with dyes like hematoxylin and eosin to distinguish different cell components like nuclei and cytoplasm. These stains help researchers visualize and study the cells under a microscope.
