Pyrenoid A protein structure found in the chloroplasts of green algae and hornworts (Anthocerophyta). Pyrenoids are associated with the storage of starch.
The characterization of photobiological hydrogen production for four marine green algae by sulfur-deprived and treated with uncoupler after dark anaerobic incubation was investigated.
All the plants we know today descended from the same ancestor: a teeny-tiny green alga — that's the singular for algae — that existed around 500 million years ago.
Today's programme was all about microalgae like spirulina, a green, edible food algae which some people call pond scum, although scientifically speaking it's an organism, meaning an animal or plant life form.
Caulerpa taxifolia, a green algae that can reach 30 centimeters long, is believed to be the largest single-celled organism in the world thanks to its unique biological hacks.
Paleobotanists are still debating what exactly the first type of land plant actually was, but they agree that it was small and moss-like, probably some kind of green algae or liverwort.
Researchers have not been able to find traces of the compounds in rocks older than that, despite the existence of fossils of a red and a green alga — both eukaryotes — dating back about one billion years.
