OPTION 1

Based on the presence or absence of granules in the cytoplasm, the leukocytes are classified into two groups:

1.           Granulocytes which have granules.

2.           Agranulocytes which do not have granules.

 

1.           Granulocytes

Depending upon the staining property of granules, the granulocytes are classified into three types:

i.            Neutrophils with granules taking both acidic and basic stains.

ii.           Eosinophils with granules taking acidic stain.

iii.          Basophils with granules taking basic stain.

 

2.           Agranulocytes

Agranulocytes have plain cytoplasm without granules. Agranulocytes are of two types:

i.            Monocytes.

ii.           Lymphocytes.
