Plasma and platelets have different densities, which allows them to be separated in a centrifuge. Because the platelets have a higher density than the serum and fibrin in plasma, they are pushed out of the plasma and collected at the bottom of the collection container.
Blood plasma contains platelets, RBC and WBC cells in them. the answer to your question is yes. plasma is the component of blood obtained after removing all the blood corpuscles like RBC,WBC and platelets so it doesnt contain platelets but there are substances called platelet rich plasma where the plasma is enriched with platelets for specific purposes
Platelet-rich plasma - is simply plasma containing platelets. When a person donates blood, it's separated in a laboratory into its components... Red blood cells - which are used to treat anaemia. White blood cells - used to boost a person's immune system. Platelets - used to help stop bleeding. Plasma - used to restore a patient's blood pressure after an accident etc. Plasma will usually contain just small amounts of platelets - unless they've been 'harvested' specifically. Blood donors with naturally-high platelet counts can be asked to donate just platelets (instead of 'whole' blood). Their blood is separated at the time of donation by a small centrifuge by their bed - and the 'unused' components of blood are returned to their body.
Plasma is the clear portion, there are also platelets, red blood cells, and other clotting factors present in the blood.
Blood Composition * Plasma * RBCs * White Blood Cells * Blood Platelets

The four major components in blood are: -Plasma -Platelets -Red Blood Cells -White Blood Cells
Blood cells, plasma, and platelets all carry blood, platelets help blood clot and move red & white blood cells around, Plasma is the liquid part of the blood that holds blood cells and gets moved around by platelets, and blood cells move around in your blood fighting infections & protecting your wounds by forming scabs.
Blood consists of plasma, blood cells, and platelets
White blood cells Red blood cells Blood plasma Platelets
Platelets or blood clotting proteins cause blood to clot.
