Final answer:
Granular leukocytes which include neutrophils, eosinophils, and basophils are classified by their staining properties with neutrophils showing light lilac granules, eosinophils having reddish-orange granules, and basophils with dark blue to purple granules.
Step-by-step explanation:
The granular leukocytes with light-staining granules that are called based on their affinity for eosin and methylene blue are neutrophils, eosinophils, and basophils. Each of these granular leukocytes is classified according to the type of dye they best absorb.
Neutrophils have small granules that stain light lilac and a multi-lobed nucleus; eosinophils have larger granules that stain best with eosin, a reddish-orange color, and a two to three-lobed nucleus; and basophils have large granules that absorb basic stains and appear dark blue or purple with a two-lobed nucleus.
