No, while copper ions can give a green color, not all green things are copper.
An insects yellowish-green "blood" gets its color from other pigments, usually found in plants eaten by the insects.
Insects and other arthropods have blood that is often red due to the presence of a pigment called hemocyanin. This pigment contains copper, which gives the blood a blue or green color when oxygenated, but can appear red when deoxygenated.
Spiders have blue blood. In human blood oxygen is bound to hemoglobin which contains iron, giving it the blood a red color. In spiders, as well as other Arthropods and Molluscs, oxygen is bound to hemocyanin which contains copper, giving its blood a blue color. The same interaction that causes oxygenated blood to color, also causes iron rust to appear reddish and the oxidized copper to appear green. However, I have noticed no color in spider blood before.
Certain species of animals, notably some mollusks, arthropods, and brachiopods, have blue blood due to the presence of hemocyanin, a copper-based protein that functions similarly to hemoglobin in vertebrates. Additionally, some species of marine worm called "ice worms" have green blood because they contain a green pigment called chlorocruorin, which also aids in oxygen transport. These adaptations are often linked to their unique environments and physiological needs.
His skin is light green in color. As is his blood, because it is copper based, instead of iron based, which is why humans blood is red.
Spiders have blue blood. In human blood oxygen is bound to hemoglobin which contains iron, giving it the blood a red color. In spiders, as well as other Arthropods and Molluscs, oxygen is bound to hemocyanin which contains copper, giving its blood a blue color. The same interaction that causes oxygenated blood to color, also causes iron rust to appear reddish and the oxidized copper to appear green. However, I have noticed no color in spider blood before.
The pennies turn green because they are open to the air, because they contain copper, and because copper turns green when oxidized.
Spock's blood is green.It is green because the oxidizing agent in Vulcan blood, the base element of his hemoglobin, is copper, not iron as it is in humans. Copper oxide (verdigris) gave Spock's blood its blue-green hue. We see this on episode "Journey to Babel" when Spock's Vulcan father, Ambassador Sarek (Mark Lenard) suffers a heart attack that requires surgery and a life-giving transfusion of T- Negative blood from Spock.In Star Trek The Original Series Dr. McCoy comments on Spock's Green Blood. Therefore his blood is Green.
Copper turns green when it oxidizes because of the formation of a greenish layer of copper oxide on its surface.
That's just nature. If it were'NT nature i'd have like pink-blue blood and you would have like black blood....
In ores. Copper ores are found in various parts of the world. Copper can be found as a metal in the ground. Normally, it is green on the outside. Most copper is not as a metal but in chemical compounds. Chalcopyrite is the most common copper ore. It is a mixture of pyrite and copper sulfide. Copper is found in small amounts in living things. Some mollusks and arthropods have blue blood because they have copper in their blood. Animals such as humans and other mammals have red blood because it contains iron. Copper is purified by electrolysis. Electricity is passed through solutions containing copper compounds, such as copper sulfate - sometimes spelt sulphate. Pure copper forms on the negative electrode.
The oxygen carrier in most mammalian blood is iron - oxygenated iron is red. In the old TV show "Star Trek", Mr. Spock's Vulcan blood was green, because in Vulcan blood, the oxygen carrier was copper - and coppers oxides are green.
Copper turns green because of sulfur pollution in the air, forming copper sulfide.
