They part cells. They are fragments of their parent cells, megakaryocytes. Parts of the megakaryocytes bud off from the membrane releasing a vesicle contaioning about 1000 platelets. Hope this explains it for you. If not ask me! :)

Neither. Blood platelets are fragments of cells. So they still have a membrane and cytosol, but only some organelles, whichever end up there by chance when a megakaryocyte splits into many plateles.
