Large agranular phagocytes are called:

a. Neutrophils

b. Basophils

c. Eosinophils

d. Monocytes

e. T-Lymphocytes

f. B-Lymphocytes

Expert Solution

There are two types of the white blood cells or leukocytes. Leukocytes are also called as phagocytes.
a) Granulocytes- contains granules in the cytoplasm which are stained either with the eosin or methylene blue.There are 3 types of granulocytes - neutrophils, eosinophils and basophils.
b) Agranulocytes- these cells do not contain granules in the cytoplasm. There are two types of agranulocytes - lymphocytes and monocytes.
Out of these two agranulocytes , monocytes are the largest leukocyte. The diameter of the monocyte is 14- 18 micron.The nucleus of the monocyte is placed either in the center of the cell or pushed to one side and large amount of cytoplasm is seen.
The diameter of the lymphocytes is smaller than the monocyte.The nucleus of the lymphocyte occupies the whole of the cytoplasm . There are two types of lymphocytes according to the size .
Large lymphocytes - diameter is 10- 12 micron.
Small lymphocytes - diameter is 7-10 micron.
So, the correct answer is option d.monocyte.

The crashing cost (per week), for the first week, for activity A is: $540, E is $545 and all other activities is : $135 (per week per activity). The crashing cost, second week and onwards, for activity A is $1080 per week, E is $1350 per week and for all other activities is...
