What is the Difference Between Megakaryocyte and Platelet?
🆚 Go to Comparative Table 🆚The main difference between a megakaryocyte and a platelet lies in their origin, function, and structure:
- Origin: Megakaryocytes are large progenitor cells that reside in the bone marrow and serve as the precursor for platelets. Platelets, on the other hand, are tiny anucleate blood cells that are derived from megakaryocytes.
- Function: Megakaryocytes are responsible for producing and releasing platelets into the bloodstream. Platelets play a crucial role in the clotting process, which is essential for preventing blood loss and maintaining proper blood vessel function.
- Structure: Megakaryocytes are nucleated,myeloid cells with a size of around 20 µm. They contain organelles and glycoproteins that are similar to those found in platelets. Platelets, however, are anucleate cells with a much smaller size.
In summary, megakaryocytes are the precursor cells that produce platelets, and both cell types are involved in the blood clotting process. Megakaryocytes are larger and contain a nucleus, while platelets are smaller and anucleate.

Comparative Table: Megakaryocyte vs Platelet
Here is a table comparing the differences between megakaryocytes and platelets:
Feature | Megakaryocyte | Platelet |
---|---|---|
Precursor/Product | Megakaryocytes are the precursors of platelets, derived from hematopoietic stem cells. | Platelets are the final product involved in the clotting process. |
Size | Approximately 20 µm. | Approximately 4-5 µm. |
Shape | Circular or ovoid. | Disk-shaped and flattened. |
Site of Production | Bone marrow. | Bone marrow. |
In summary, megakaryocytes are larger cells that give rise to platelets, which are smaller and play a crucial role in blood clotting. Both cell types are produced in the bone marrow, but they have distinct shapes and sizes.
