A blood sample contains cells that lack nuclei and most organelles but are packed with a red protein. These cells have a distinctive biconcave disc shape. What are these cells, and why do they have this unusual structure?
Question 3 options:

Red blood cells specialized for oxygen transport with maximum hemoglobin space

White blood cells that have been damaged by disease or infection

Plant cells that accidentally contaminated the blood sample during testing

Bacterial cells that have adapted to survive in the bloodstream

Answer: Red blood cells specialized for oxygen transport with maximum hemoglobin space.

Explanation: Mammalian erythrocytes lack nuclei and most organelles so more room is available for hemoglobin (the red oxygen‑binding protein). Their biconcave disc shape increases surface‑area‑to‑volume ratio (faster O2/CO2 diffusion) and provides flexibility to squeeze through narrow capillaries.
