Vedclass · Answer

(B) The blood of an earthworm $(Pheretima)$ is red in colour.This red colour is due to the presence of the respiratory pigment haemoglobin.In earthworms,haemoglobin is not contained within blood corpuscles (like in humans) but is dissolved directly in the blood plasma.Therefore,the correct description is that the blood is red in colour due to dissolved haemoglobin in the plasma.
