Answer 1

Ans.10) Granulocytes contain granules in their cytoplasm that are made visible by staining. They are of three types i.e eosinophils, basophils and neutrophils

Eosinophils: The nucleus of eosinophils is bilobed and have large granules in the cytoplasm. The granules strain red-orange with acidic dyes such as eosin

Basophil: The nucleus of basophil is bilobed and have large granules. The granules are stain blue-purple with basic dyes such as hematoxylin.

Neutrophils: The nucleus of neutrophil is divided into 3-5 lobes. They contain small and evenly distributed granules that are stain slightly pink.

Ans.11)

a) Leukocytosis: Leukocytes is also called white blood cells(WBC). WBC protects the body against foreign agents. The increase in the number of white blood cells above 10,000/microliter which is higher than the normal is termed leucocytosis.

b) Leukopenia: The abnormally decrease in the number of white blood cells below 5000/microliter which is lower than the normal is termed leukopenia.

c) Leukaemia: Leukaemia is a cancer of the blood cells( RBC, WBC and platelets)
