It’s something seen in science fiction tv shows and movies all the time, aliens having different coloured blood.

Whether it works the same as human blood isn’t mentioned but considering how its shown it must do something similar.

Could blood be a different coloured depending on what its based on

A spiders blood is blue.

Yes. Lobsters, humans, spiders etc. have different coloured blood

Yeah lots of different animals right here on earth have non-red blood.

Great web link.

In Star Trek, Spock’s blood is supposed to be green because the oxygen carrying molecule in his blood is based on copper rather than iron.

From web link, there are copper-containing oxygen carriers, but they are blue.

“The blood of some invertebrates contains hemocyanin instead of hemoglobin. Like hemoglobin, hemocyanin transports oxygen and is a protein that contains a metal. However, hemocyanin contains copper instead of iron. It’s blue in its oxygenated form and colorless in its deoxygenated form. A hemocyanin molecule contains two copper atoms, which together bind to one oxygen molecule. Hemocyanin is the respiratory pigment in molluscs (such as snails, slugs, clams, octopuses, and squids), and in some arthropods (such as crabs, lobsters, and spiders). The pigment is found in the liquid hemolymph instead of being trapped in cells.”.

Plant blood is usually clear or white, but not always.

Which makes me wonder. Would plants grow better if they were genetically engineered to have hemoglobin in their sap? Better oxygen carrying capacity may mean faster growth.

Plants prefer CO2 …

Nitrogen fixing plants (plants unable to extract nitrogen from air on their own) contain heme (a compound found in haemoglobin) in their roots. That doesn’t answer your question.

I thought nitrogen fixing plants did extract nitrogen from the air, hence increasing nitrogen in the soil.

There are symbiotic bacteria which do the nitrogen extraction. The plants use leghemoglobin to transport oxygen to their root system to keep the bacteria living in the roots alive.

Something like that… not an expert.

Nor me. But I do recall nitrogen fixing as referring to plants that actually increase nitrogen in the soil by extracting it from the air, not just refining or concentrating nitrogen already in the soil.

I only know of this stuff because I vaguely remembered reading about “the Impossible Cheeseburger”.

“This is achieved using a chemical compound known as heme — a protein that can both be found in haemoglobin, the red pigment in blood, and the roots of nitrogen-fixing plants. These plants — which include legumes — are unable to extract nitrogen from the air on their own, so they enlist the aid of symbiotic bacteria called rhizobia, which live in their root nodules. These bacteria help the plants extract and store nitrogen.

“Heme also contains iron which, when exposed to oxygen, turns red — just like blood — and also creates those meat flavours.

“’ is basically 99 percent of the secret to meat flavor. Heme is the molecule that makes meat taste like meat. It’s the reason meat tastes like nothing else. It’s the reason why red meat, which has more heme, tastes meatier to people than white meat,” Brown said.’”

https://en.wikipedia.org/wiki/Leghemoglobin

> Leghaemoglobin (also leghemoglobin or legoglobin) is an oxygen carrier and hemoprotein found in the nitrogen-fixing root nodules of leguminous plants. It is produced by legumes in response to the roots being colonized by nitrogen-fixing bacteria, termed rhizobia, as part of the symbiotic interaction between plant and bacterium: roots not colonized by Rhizobium do not synthesise leghemoglobin. Leghemoglobin has close chemical and structural similarities to hemoglobin, and, like hemoglobin, is red in colour.

Thanks for that.
