Question

Which of the following organism has "White Blood" ?

  1. Lizard
  2. Cockroach
  3. House Bug
  4. Mosquito

Answer:

Option B: Cockroach

Detailed Solution:

The correct answer is “Cockroach”.

Cockroach has "white blood".

While it's not technically white, the blood of cockroaches is a pale, yellowish-green color due to the absence of red blood cells and hemoglobin. Instead, they rely on a different respiratory pigment called hemocyanin, which is blue when oxygenated but colorless when deoxygenated. This gives their blood a pale appearance.
