A blastetodisc is a single-layer embryonic disc, in which, after the appearance of cells, there is a rotation of 90 degrees and there is no growth, and there is also no neural tube. Now I will tell you about one amazing organism that appeared as a result of evolution as a result of incomplete cell division - blastodisc. Blastodiscs are also known as pieces, which are currently the smallest living organism on Earth. Blastodiscs are single-celled organisms that arose through evolution 4.5 billion years ago. How did it all start? At the time of their origin, blastodiscs were the result of one of the earliest stages of life on our planet. Blastodisks are one of the first organisms to appear after the “Great Explosion” - the beginning of the formation of the Earth. Initially, Blastodisks formed and grew at a temperature of about 120°C, and were also under conditions of increased pressure - about 30 atmospheres due to the explosive transformation of energy under these conditions. It was these conditions that influenced and contributed to the emergence of single-celled organisms for the first time. After this, the Earth underwent cooling, and blastodisks already became an integral part of its biosphere. Today we can see Blastodiscs in the form of a single unicellular organism, ready for a life cycle. But once upon a time, the number of these organisms was so small and huge that it was completely impossible to estimate their exact sizes. But then how does modern life exist now, and all living beings on Earth appeared some time after the origin of the Universe? Like any of us, they evolved from smaller, single-celled organisms! Blastodisks left their mark on the history of the development of life on Earth, forming the foundations of all life.
Blastodiscs are structural elements that are formed during the embryonic development of the amniotic environment in animals belonging to the placental subtype. The function of the blastodisc is to maintain the integrity of the trophoblast and the formation of the primary villous layer of the chorion[
