Solution
Platelets and White Blood Cells are found in the blood along with other blood cells and plasma. Following are the differences between platelets and white blood cells:
| Platelets | White Blood Cells |
|---|---|
| Platelets are colorless, enucleated (lacking a nucleus), and oval or round shaped structures in the plasma. | WBCs are white-colored, nucleated, and irregularly shaped structures in the plasma. |
| In the body of a healthy human being, number of platelets varies from 2.5 lakhs to 4.5 lakhs. | In the body of a healthy human being, number of WBCs ranges from 4000 to 11000 per cubic mm. |
| The life span of Platelets is about 5 to 7 days. | The life span of WBCs is only a few days. |
| Its important function is to help in the coagulation or clotting of blood by releasing a chemical called thromboplastin. | Its major function is to protect the human body from foreign bodies by producing antibodies. |
| The low number of platelets in the human body causes a diseased condition called Thrombocytopenia. | The low number of WBCs in the human body causes a diseased condition called Leukopenia. |
