Erythrocytes, or red blood cells, are flattened and circular, lack a nucleus, mitochondria, and ribosomes, and are red in color because of the presence of hemoglobin. Eosinophils (A) and basophils (B) are types of white blood cells with nuclei and other organelles. Lymphocytes (C) are also a type of white blood cell with a round nucleus, but they are not red in color. Platelets (E) are cell fragments involved in blood clotting, but they are not red in color and do not contain hemoglobin.
