Question

Quizplus · Accepted Answer

The surface of red blood cells is indeed covered with molecules called antigens, and when antibodies bind to these antigens, it can result in agglutination (clumping together) of cells. The other statements are incorrect. Platelets do not have antibodies on their surface, and blood groups are named for the antigens present on red blood cells, not the antibodies present in the blood.
