What is the structural characteristic of a eosinophils?
They contain a bilobed nucleus and their granules stain red, due to the eosin dye. Plus, the granules themselves look almost crystalline. Don't get them confused with basophils which also have a bilobed nucleus BUT basophils granules do not stain well (and when they do they stain blue) in comparision.

How can granulocytes be identified from agranulocytes?
Granulocytes can be identified when their cytoplasmic granules are stained with Wright's stain. Agranulocytes do not have cytoplasmic granules so they will not have stained granules.
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 confirmatory test could be performed to identify the oval fat bodies?
A confirmatory test that could be performed to identify oval fat bodies is the Sudan III stain test, which is used to specifically detect lipid material such as fat. Sudan III stains fat droplets orange to red under a microscope, aiding in the identification of oval fat bodies in urine sediment.
What is Sudan black b stain is use for in bone marrrow?
Sudan black B stainThis stain distinguishes between acute lymphoblastic leukemia (cells stain positive) and acute myeloblastic leukemia (cells stain negative).
What stain is used amyloplasts?
Iodine stain is commonly used to detect amyloplasts due to their ability to stain starch granules purple-black.
What color does Sudan IV stain lipid?
it produces a brick/dark red stain.
Which white blood cell type has granules that stain dark purple in response to alkaline dye?
Basophils are the white blood cell type that has granules that stain dark purple in response to an alkaline dye. These granules contain substances such as histamine and heparin, which play a role in inflammatory reactions and allergic responses.
Sudan III is used to detect the presence of what macromolecules?
Sudan III is used to detect the presence of lipids (specifically triglycerides) in various samples, such as food, blood, and forensic samples. It is commonly used in experiments to visually identify the presence of fats and oils due to its ability to stain lipid-rich substances.
If you stain a wet mount of living cells with iodine what are you most likely to see under a microscope?
Iodine is commonly used to stain starch granules within cells. Therefore, if you stain a wet mount of living cells with iodine, you are most likely to see starch granules within the cells stained with a dark color under the microscope.
The granular leukocyte that stains red is?
EosinophilA granular leukocyte, the granules of which have an affinity for the acid dye of Wright's stain (eosin). The granules are large, round, uniform in size, red-orange in color and are shiny and refractile.
