Vedclass · Answer

(D) All living organisms require respiration to survive. The cockroach does not rely on its blood (haemolymph) for oxygen transport because it lacks respiratory pigments like haemoglobin. Instead, the cockroach possesses a specialized network of tubes called the $tracheal 	ext{ } system$. Air enters through openings called spiracles and travels through tracheae and tracheoles, delivering oxygen directly to the tissues. Therefore, the blood does not play a role in the transport of respiratory gases.
