Wrong Answer

The correct answer is: The cytoplasm contains haemoglobin.

Blood cells carry oxygen to different parts of the body. Oxygen is required for aerobic respiration in organs. Red blood cells can transport oxygen around the body because oxygen binds to haemoglobin. These cells do not have nuclei to allow room for haemoglobin.

Red blood cells have a biconcave shape to maximise the efficiency oxygen absorption. A biconcave shape increases the surface area in relation to volume. It does not have anything to do with arteries.
