Final answer:
Neutrophils have small granules that stain light lilac, not dark blue, and exhibit a distinctly lobed nucleus. It is basophils that have large, dark blue-staining granules.
Step-by-step explanation:
The statement that neutrophils' granules stain dark blue and are easily identifiable on stained blood smears is false. Neutrophils are the most common type of granulocytes and are known for their granules that stain a light lilac color when treated with chemically neutral stains. The neutrophils contain numerous but very fine granules and possess a nucleus that has two to five lobes, known for its lobed appearance. Neutrophils are larger than erythrocytes, usually about 10-12 µm in diameter, and play a critical role in the immune response by defending the body against invading pathogens. In contrast, it is the basophils that have large granules which stain dark blue to purple and can make it difficult to see their two-lobed nucleus.
