In 1888, the biologist Henry Ori found some spotted quail eggs in a swamp lake, some of them even green. At the time, Henri wrote in his notes that there was a bright, uniform green color on the intima of the quail eggs, and that the green color that adhered to the membrane was tiny spherical green algae. Ori believes that this is the best evidence for the symbiosis between the algae and the green algae. The mutual dependence of alfalfa and green algae maintains a symbiotic relationship.
Ouerui’s conclusion is correct. The quail egg has formed a partnership with Chlorella, but his opinion on a key issue is wrong. He believes that the green algae is only very close to the quail eggs and thus forms a symbiotic relationship. In fact, this is not the case.
Twelve years later, Ryan Kell of Darmisch University found that Chlorella was actually actively invading quail eggs, and became part of the quail embryos and grew together.
The green algae settle in the embryos. The embryos can use the solar energy through the green algae. It is one of the animals that can use solar energy and live a life like a plant to obtain energy directly from the sun.
Spotted quail embryos are not the only animals that form a symbiotic relationship with green algae. Emerald green sea cucumbers take green algae and steal the photosynthetic genes of green algae from the green algae genome. Coral reefs also form a symbiotic relationship with green algae, acquiring energy through green algae. Many other animals have similar symbiotic lifestyles from sponges to worms. However, baboons are the only vertebrates that have a symbiotic relationship.
Since Orie discovered this phenomenon, several scientists have begun to carefully study the symbiotic pattern of quail embryos and green algae. It has been found that larval eggs with green algae are more likely to hatch crickets, and hatching takes less time, and embryos with green algae hatch larger and develop better. This process relies on sunlight. Chlorella needs sunlight to synthesize synthetic nutrients and provide oxygen to the embryos. If the quail embryos sink into the dark, they cannot get green algae. In return, the excrement during the development of the cockroaches is devoted to the green algae. If Chlorella accidentally enters an unfertilized egg cell, then the green algae cannot grow.
It seems that these relationships have been sorted out, but Conil is the first scientist to show where Chlorella is located. He observed many green embryos. He used practical video recording techniques to record the entire development process of the quail embryo. After about two weeks of embryonic development, he began recording when the chlorella entered the embryo. Conil then sequenced the green algae in the embryo and removed the green algae from the embryo. In the end, Conil puts a glowing molecule on the DNA of the green algae and then puts it into the embryo. As a result, it was found that the entire body of the baboon was shining.
After hatching, most of the green algae have disappeared from the larvae to the adults. The bodies of adults are opaque and most of them live under the ground. This is an environment that is not conducive to green algae. Conil believes that in the dark environment, the green algae slowly died, and finally leave you with a sumptuous feast, it is also regarded as the last grace of the green algae.
How green algae enters quail eggs has always been a mystery. Maybe Chlorella will track the excreta of the cockroach to find fertilized eggs. Once found, the green algae enter the embryo from the blastosphere. Sometimes green algae can be passed down from generation to generation. Conil found the DNA of green algae in the fallopian tubes of several female ticks. This is in conflict with the fact that the green algae enter the embryo from the blastocyst, but may be passed down from generation to generation. The mother of the deaf will remove the green algae from the egg cells and help the embryo grow.
In the vertebrate world, this symbiosis of the baboon is very unique. Under normal circumstances, the vertebrate's immune system attacks foreign organisms, and the green algae that enters the embryos should be cleared by the immune system. Scientists speculated that there may be two possible exceptions. First, green algae may have entered the embryo just before the development of the immune system. Second, maybe there is a unique immune system. This may be related to the unique regenerative ability of alfalfa, which can quickly regenerate bodily broken limbs, which means that their pattern of identifying their own cells is different from other animals. Perhaps it is this slack identification system that gives Chlorella an opportunity.
There is also an ultimate, simpler possibility. No one has found other animals that rely on solar energy simply because others have not observed it carefully. Now Conair has already had a good start. Maybe other scientists will find similar animals in the future.
