Question

'S ' shaped nucleus is present in
A. Monocytes
B. Neutrophils
C. Eosinophils
D. Basophils

Answer 1

Hint: White blood cells in human blood plasma have significant importance; they help recognising foreign antigens in the body and switch the antibodies to fight against the foreign body. There are different types of white blood cells called granulocytes. They carry their own importance with distinct nuclei inside the cells. The different shape of the nucleus in the granulocytes helps in the unique action of the cells. They can be differentiated depending on the shape of nucleus

Complete answer:
Monocytes: It is a type of white blood cells. With no granules inside the cell and the colour of cytoplasm is stained blue which makes it distinct. They are considered as the key cells of the immune system the nucleus forms a dense mass, resembling bean shape.
So, option A is not correct
Neutrophils: this is also a type of white blood cells. Neutrophils are the main cells as most of the immune response action is carried out by neutrophils hence they are considered as policemen of the blood cells. It contains granules and the nucleus is divided into 2-5 lobes.
So the option B is not correct as it contains lobes
Eosinophils: This type of white blood cell is observed in high numbers. Eosinophils are released in response to allergy, infection, or in the area of inflammation. And the shape of eosinophils is kidney shaped.
So, option C is not correct
Basophils: This type of white blood cell is produced from the bone marrow. They help in blood clotting by releasing heparin. They are naturally occurred inside the human body. The count of basophils must be maintained in order to stay protected from allergies. The shape of the basophil nucleus is s’ shape.
So, the correct answer is “Option D”.

Note:
The basophil cells help in the proper contraction of the muscles. And help in releasing the important immune response hormones. Proper nutrient food mist is taken to maintain the levels of white blood cells as they are important for immunity. Mostly vitamin C and green leafy vegetables are recommended.
