Assertion :Blood is colourless in the insects Reason: Insect blood has no role in O2 transport
B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Reason: In general animals use blood to transport various elements, throughout the body. In human beings blood is also used to carry oxygen from the lungs to the tissues. The oxygen is attached to a substance called hemoglobin, it is red color. Insects also use blood, but it is not used to carry oxygen. The insect blood does not contain hemoglobin and is not red color. Insect blood is either colorless and pale yellow or green.
