Final answer:
Neutrophils comprise approximately 50-70 percent of the total leukocyte count. They are characterized by their lobed nuclei and light lilac granules when stained.
Step-by-step explanation:
Neutrophils are a type of white blood cells (WBCs) that play a crucial role in the body's defense mechanism. They normally represent about 50-70 percent of the total leukocyte count in the bloodstream.
These cells are identifiable under a microscope by their distinct lobed nucleus, which can have two to five lobes, and their fine granules that appear light lilac when stained with neutral dyes. The diameter of a neutrophil is roughly 10-12 µm, making them larger than erythrocytes (red blood cells).
