Final answer:

Platelets, or thrombocytes, are non-nucleated fragments of cytoplasm released from megakaryocytes in the bone marrow. They play a vital role in blood clotting and prevent excessive bleeding.

Step-by-step explanation:

Platelets, also known as thrombocytes, are non-nucleated fragments of cytoplasm released from megakaryocytes in the bone marrow. They play a crucial role in blood clotting and preventing excessive bleeding. Each platelet is a disc-shaped cell fragment enclosed by a plasma membrane, formed from the disintegration of larger cells called megakaryocytes. Thrombocytes release at the wound site and form a platelet plug or clot, which stops the loss of blood.
