WebbPlatelets are fragments of large cells called megakaryocytes. Fragments are essential for blood clotting. Can plugs up any holes or tears. Die every ten days but are constantly regenerating. Megakaryocytes form due to repeated mitotic cycle that do not perform cytokinesis, so the result is one huge cell with a multilobed nucleus. WebbRather, they are fragments of extraordinarily large cells (up to 60 um in diameter) called megakaryocytes. Platelets are about one-fourth the diameter of a lymphocyte. In blood smears, each platelet exhibits a blue-staining outer region and an inner area containing granules that stain purple.
