Verified step by step guidance

Understand the terms 'biconcave' and 'anucleated'. 'Biconcave' refers to a shape that is concave on both sides, like a doughnut without a hole. 'Anucleated' means lacking a nucleus.

Identify which blood cells have a biconcave shape. Red blood cells (erythrocytes) are known for their distinctive biconcave shape, which increases their surface area for gas exchange.

Determine which blood cells are anucleated. Red blood cells are anucleated, meaning they do not have a nucleus, which allows more space for hemoglobin to carry oxygen.

Consider the other options: platelets (thrombocytes) are cell fragments involved in clotting, leukocytes (white blood cells) have nuclei and are involved in immune response.

Conclude that the terms 'biconcave' and 'anucleated' specifically apply to red blood cells, as they match both characteristics.
