Question

Why is cockroach blood white?

Answer 1

Cockroach blood is white because:

1. Cockroaches do not need haemoglobin to transport oxygen, their blood is not red.
2. Their bloodstream is also not used to store oxygen.
3. They employ tracheae, a network of pipes, to transport oxygen and remove carbon dioxide from their tissues
4. . As a result, the blood colour is determined by other factors.
5. Cockroach blood does not surround haemoglobin because it has different ways of transporting oxygen directly into the tissues.
