• B. $\begin{array}{cc}\text{1}& \text{Monocyte}\\ \text{2}& \text{Eosinophil}\\ \text{3}& \text{Basophil}\\ \text{4}& \text{Neutrophil}\\ \text{5}& \text{Lymphocyte}\end{array}$
• C. $\begin{array}{cc}\text{1}& \text{Neutrophil}\\ \text{2}& \text{Lymphocyte}\\ \text{3}& \text{Basophil}\\ \text{4}& \text{Monocyte}\\ \text{5}& \text{Platelets}\end{array}$
• D. $\begin{array}{cc}\text{1}& \text{Eosinophil}\\ \text{2}& \text{Monocyte}\\ \text{3}& \text{Basophil}\\ \text{4}& \text{Platelets}\\ \text{5}& \text{Neutrophil}\end{array}$

Answer 1

The correct option is A $\begin{array}{cc}\text{1}& \text{Basophil}\\ \text{2}& \text{Eosinophil}\\ \text{3}& \text{Neutrophil}\\ \text{4}& \text{Monocyte}\\ \text{5}& \text{Lymphocyte}\end{array}$

The white blood cells are divided into 5 groups based on their functions, their nuclei and the stain they take up during in-vitro observation. Basophils, eosinophils and neutrophils have a lobed nuclei. The cytoplasm of basophil takes up a basic blue stain, that of eosinophil takes up an acidic red stain, and the cytoplasm of neutrophil remains unstained. Monocytes and lymphocytes have unlobed nuclei. Monocytes are bigger with bean-shaped nuclei. Lymphocyte has a large nucleus covering most of the cell space.
