Answer :

Final answer:

Platelets, or thrombocytes, are anucleated cell fragments derived from megakaryocytes that aid in blood clotting.


Explanation:

Platelets, also known as thrombocytes, are small anucleated cell fragments that play a crucial role in blood clotting. These fragments of cytoplasm are derived from megakaryocytes in the bone marrow. They lack a nucleus and are essential in preventing bleeding by clumping together at the site of a blood vessel injury.
