Why is insect blood green or yellow?

Answer 1

Insect blood doesn't transfer oxygen. That means it doesn't need hemoglobin, which is what makes blood appear red. Insect blood is only about 10% hemocytes (blood cells), most of it just watery plasma called hemolymph, tending to be green or yellow.

Answer 2

Because it has no haemoglobin (the oxygen-carrying molecule which gives blood its red colour). Instead, insect blood -- more properly called haemolymph -- uses haemocyanin to carry oxygen, and this is colourless.

Answer 3

Insect blood, called hemolymph, is green or yellow due to the presence of the oxygen-carrying protein hemocyanin. Hemocyanin contains copper, which gives the blood its color. This is different from human blood, which contains iron-based hemoglobin.

Answer 4

why is it that the blood of an insect is not red

Answer 5

Insect blood is not red, like human blood is, because they do not have the same kind of blood cells in their bodies as we do.

Answer 6

Answer 7

Because it doesnt have iron.
