Final answer:
Stained leukocytes with visible cytoplasmic granules are called granular leukocytes, which include neutrophils, eosinophils, and basophils. They can be identified by their distinctive granule staining and lobed nuclei.
Step-by-step explanation:
Stained leukocytes with visible cytoplasmic granules are called granular leukocytes. These leukocytes include neutrophils, eosinophils, and basophils. When observing blood slides, granular leukocytes can be identified by the clear presence of granules within their cytoplasm. Neutrophils have small granules that stain light lilac, eosinophils have slightly larger granules that stain reddish-orange, and basophils have large granules that stain dark blue to purple. All of them have a lobed nucleus.
In contrast, agranular leukocytes contain smaller, less-visible granules and a simpler-shaped nucleus without distinct lobes. This group includes lymphocytes and monocytes. However, the question specifically asks about leukocytes with visible cytoplasmic granules, which refers to granular leukocyte
