उत्तर
Platelets are actually not true cells but merely circulating fragments of cells. But even though platelets are merely cell fragments, they contain many structures that are critical to stop bleeding.

They contain granules that can secrete other proteins required for creating a firm plug to seal blood vessel breaks.
