What is the properties of platelets?

Answer 1

Platelet Structure

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 proteins on their surface that allow them to stick to breaks in the blood vessel wall and also to stick to each other. They contain granules that can secrete other proteins required for creating a firm plug to seal blood vessel breaks. Also platelets contain proteins similar to muscle proteins that allow them to change shape when they become sticky.

Answer 2

Blood platelets have structures that are round biconvex cells. Platelets do not have nuclei but contain granules. Platelets also are called thrombocytes.

Answer 3

Platelets are irregular, clear fragments of large cells called megakarocytes. They are small also.
