Final answer:
Granulocytes include neutrophils, eosinophils, and basophils, all of which have granules in their cytoplasm. Monocytes are agranulocytes, therefore do not contain these granules and are not considered granulocytes.
Step-by-step explanation:
Granulocytes are a type of white blood cell characterized by the presence of granules in their cytoplasm and a lobed nucleus. These include neutrophils, eosinophils, and basophils. PMN is another name for neutrophils, thus they are also considered a type of granulocyte. In contrast, monocytes are a type of agranulocyte, which means they do NOT include the granules characteristic of granulocytes. Monocytes mature into macrophages and dendritic cells, playing a crucial role in the immune response, but they are not categorized as granulocytes.
