Question

given the following images of an actual white blood cell on the left and a model of the same white blood cell type on the right:

select they type of white blood cell they represent from the listing below.

neutrophil
lymphocyte
basophil
monocyte/macrophage
eosinophil

Explanation:

Analyze cell morphology

Using the White Blood Cells knowledge point, we examine the visual characteristics of the actual cell on the left and the model on the right. The actual cell is heavily packed with large, dark purple/blue granules that obscure the nucleus.

Identify the specific leukocyte

Using the Basophil Morphology knowledge point

• The presence of dense, coarse, dark purple-blue granules overlying a multi-lobed (often S-shaped or bilobed) nucleus is the classic hallmark of a basophil.
• The model on the right highlights this characteristic S-shaped or irregular lobed nucleus, which is typically hidden by the prominent granules in a real blood smear.
• Therefore, the cell type represented is a basophil.

Answer:

• neutrophil
• lymphocyte
• basophil (Correct answer)
• monocyte/macrophage
• eosinophil
