Explanation:
Platelets are one of the three types of blood cells. Platelets are involved in the formation of blood clots. Platelet vesicles have clotting factors and other substances required for the formation of a platelet plug during homeostasis. A break or damage in the lining of blood vessels exposes the underlying collagen fibers and the connective tissues. Platelets adhere to these fibers to initiate the formation of a platelet plug. These adhered platelets release substances to trigger the other platelets to join and form aggregate. This aggregate of platelets is called a platelet plug.

Rather, passive transport relies on the innate permeability of the cell membrane and its component proteins and lipids.
