Correct Answer: thrombocytes

Solution : The correct option is thrombocytes .

Thrombocytes are another name for blood platelets. Thrombocytes are tiny, disc-shaped, nucleus-free cell fragments that are essential to hemostasis, the process of clotting blood. They help stop excessive bleeding by producing blood clots at the site of damage and are made in the bone marrow. Thrombocytes cling to the injured blood vessel walls and secrete chemicals that set off the clotting cascade, causing a blood clot to form and close the wound.
