Detailed explanation-1: -Eosinophils are another type of granulocyte with cytoplasms that contains large granules that generally stain bright red with a red dye eosin, and can also stain with other acid dyes, hence also known as acidophils. The size of eosinophils is similar to that of neutrophils (about 12 m).

Detailed explanation-2: -The acidic stain used to colour the cytoplasm of eosinophils is eosin and has a red colour.

Detailed explanation-3: -Eosin is an acidic dye for staining cell cytoplasm, collagen, and muscle fibers. Eosinophilic describes the appearance of cells and structures seen in histological sections that take up the staining dye eosin.

Detailed explanation-4: -Eosin is a bright red synthetic dye produced by the action of bromine on fluorescein and stains basic proteins due to its acidic nature.

Detailed explanation-5: -Basic dyes stain basophilic structures (e.g. nuclei, ribosomes and GAGs). Acid dyes stain acidophilic structures (e.g. cytoplasm, basic tissue proteins).
