Answer to Question 1

ANS: D
The band neutrophil is capable of chemotaxis (i.e., it can move along a chemical gradient). It is an almost mature polymorphonuclear neutrophil, and has full motility, active adhesion properties, and some phagocytic ability.

Answer to Question 2

ANS: D
Eosinophil granules differentiate the eosinophils from the neutrophil at the early myelocyte stage. Before this, the myeloblast and promyelocyte stages are indistinguishable by morphology.
