Respiratory Pigment Present In Cockroach Is (A) Haemozoin.(B) Haemoglobin. (C) Haemocyanin.(D) None Of These.

The correct answer is (C) Haemocyanin.

The respiratory pigment of cockroaches is called hemolymph.

Hemolymph is colourless fluid equivalent to blood in most invertebrates. It is also called the blood of insecta s.

Hemolymph is composed of fluid plasma and a high concentration of free amino acids.

The main component of hemolymph is water, which functions as a solvent for a variety of molecule and it lacks respiratory pigment. Therefore, it is white in colour.
