Plasma and platelets are both components of blood, but they are different in that the former is the non-cellular part of blood and the latter is the cellular part.
Blood is mainly composed of plasma and blood red blood cells. Plasma is light yellow in color and is the liquid component, which contains clotting factors, and blood cells are suspended in plasma, whose main function is to transport blood cells, life-sustaining substances and waste products. Platelets, together with red blood cells and white blood cells, constitute blood red blood cells, and the main function of platelets is to coagulate and stop bleeding.
To summarize, the above two substances are two different substances with different functions and uses, but the common point is that they are all components of human blood.
