Example of bacteria for metachromatic granules?
Corynebacterium diphtheriae is an example of a bacterium that contains metachromatic granules. These granules are composed of polyphosphate polymers and are typically observed in the metachromatic staining method where the granules appear blue or purple when stained with methylene blue.
What cell has a bilobed nucleus and red staining granules that become abundant during allergies and parasitic infections?
Eosinophils are the cells with a bilobed nucleus and red staining granules. They are involved in immune responses to allergies and parasitic infections by releasing substances to combat these invaders.
What is gram stain of rotavirus?
Rotavirus is a non-enveloped virus that does not stain well with the traditional Gram stain method. Instead, it is typically visualized using specialized staining techniques like electron microscopy or immunofluorescence staining.
What is silver impregnation staining?
Silver impregnation staining is a histological technique used to visualize nerve fibers, reticular fibers, and certain fungi in tissue specimens. It involves impregnating the tissue with a silver solution, which binds to the target structures, allowing them to be visualized under a microscope. This staining method is particularly useful for studying the morphology and distribution of these structures in various tissues.
What are effects of staining onion cells with dilute iodine solution?
It affects the end results. If you look at the cell under a microscope, you will see that the section where the solution of the iodine has been placed it will appear different from the others. It might be a seperate colour or it could vary in size.
White blood cell with dark-staining granules that have an affinity for basic dyes?
The description matches eosinophils, a type of white blood cell. Eosinophils are characterized by dark-staining granules that can be visualized under a microscope by basic dyes such as eosin. They play a role in allergies and parasitic infections.

What leukocyte is formed in bone marrow and having neutral staining granules?
That would be a Neutrophil. :)
What cell has a bilobed nucleus and red staining granules that become abundant during allergies and parasitic infections?
Eosinophils are the cells with a bilobed nucleus and red staining granules. They are involved in immune responses to allergies and parasitic infections by releasing substances to combat these invaders.
What is amido black?
Amido black is a dye commonly used for staining proteins in electrophoresis gels. It binds specifically to proteins and can be visualized after staining to help identify the presence and quantity of proteins in a sample.
What are the gram reaction of mycobacterium?
Mycobacteria are typically Gram-positive, but their cell wall structure is unique and contains high lipid content, making them resistant to Gram staining. They are best visualized using acid-fast staining methods, such as the Ziehl-Neelsen or Kinyoun stains.
What is gram stain of rotavirus?
Rotavirus is a non-enveloped virus that does not stain well with the traditional Gram stain method. Instead, it is typically visualized using specialized staining techniques like electron microscopy or immunofluorescence staining.
What blood cell granules stain bright orange red when you use Wright's stain?
Eosinophils are the blood cells whose granules stain bright orange-red when using Wright's stain. This staining highlights their role in immune responses and inflammation.
What is silver impregnation staining?
Silver impregnation staining is a histological technique used to visualize nerve fibers, reticular fibers, and certain fungi in tissue specimens. It involves impregnating the tissue with a silver solution, which binds to the target structures, allowing them to be visualized under a microscope. This staining method is particularly useful for studying the morphology and distribution of these structures in various tissues.
Can a virus be gram stained?
No, viruses cannot be gram stained because they are too small to be visualized under a light microscope, which is required for performing gram staining. Gram staining is a technique used to classify bacteria based on their cell wall composition and structure.
What are effects of staining onion cells with dilute iodine solution?
It affects the end results. If you look at the cell under a microscope, you will see that the section where the solution of the iodine has been placed it will appear different from the others. It might be a seperate colour or it could vary in size.
What is the purpose of adding Lugol's iodine to potato slide?
Adding Lugol's iodine to a potato slide is a common staining technique used to visualize starch granules. Lugol's iodine interacts with the starch in the potato cells, turning the granules a distinct blue-black color, making them easier to observe under a microscope. This staining process helps in identifying the presence of starch in the potato cells.
