Question

question 13
identify the blood cells indicated by the black arrow.
a erythrocytes
b thrombocytes
c platelets
d neutrophils

Explanation:

Neutrophils are a type of white blood cell. They have a multi - lobed nucleus (which can be seen as the segmented blue structure in the image after staining). Erythrocytes (red blood cells) are biconcave discs without a nucleus. Thrombocytes (platelets) are much smaller cell fragments. Platelets are also smaller than neutrophils and do not have a multi - lobed nucleus like the cells indicated by the arrows.

Answer:

D. neutrophils
