Question

Why the blood of insect is colourless ? ?

Answer 1

this is because they do not have haemoglobin. the function of heamoglobin that is carrying oxygen is done by elaborate system of tubes and air sacs.

Answer 2

Answer:

Oxygen is bound to a substance called hemoglobin, which has a characteristic red color. Insects also have blood, but it is not used to carry oxygen. Instead, oxygen is distributed through an elaborate system of tubes and air bags. Therefore, insect blood has no hemoglobin and is not red.

Explanation:

Insect blood is known as hemolymph and is colorless because hemoglobin is not present in its blood. The circulatory system of insects is of the open type, that is, it has no veins and arteries. Oxygen is directly transported to the tissue through the tracheoles.

the statement and the reason are correct but the reason is not a correct explanation of the statement because insect blood is colorless due to the absence of hemoglobin.

Insect blood is colorless due to the absence of hemoglobin. Also, insect blood plays no role in oxygen transport because oxygen transport requires the attachment of oxygen molecules to hemoglobin. Since insect blood is not made up of hemoglobin, its blood has no role in oxygen transport. Oxygen transfer in insects occurs through tracheoles, i.e. a complicated system of tubes and air sacs. So both the statement and the reason are correct, but the reason for the statement is not the correct explanation.

The statement that insect blood is colorless is correct and the reason that insect blood plays no role in oxygen transport is correct. In insects, oxygen is transported through a complicated system of tubes and air sacs, but not by blood.

The statement i.e. insect blood is colorless is correct because insect blood lacks a red pigment called hemoglobin and the reason is also correct.
