When gastrulation occurs by epiboly, the Blastopore is generated at the vegetative pole. The Blastopore is a pit-like thing in the side of the embryo, through which cells fated to be endodermal flow so that they leave the outer surface of the embryo and can create a new inner surface. In this case, it is called "virtual" Blastopore. It describes the primitive streak of avian or mammalian embryos during archenteron invasion. Sometimes this movement is incomplete and open pores do not develop. The Blastopore is formed by the inward movement of the endoderm and mesoderm cells of the archenteron during invasion of the archenteron. In many animals, the Blastopore becomes the anus, but it may close at the end of the archenteron invagination and reappear at or near the same site. Let us proceed to learn more about Blastopore development and Blastopore functionīlastopore means a mouth-like opening of the archenteron on the surface of the embryo during the invagination of the archenteron. And in many animals, the Blastopore transforms to become the anus or the mouth an opening in the rear end is more likely to be formed. And Blastopore is one of the great examples to learn how it is a mouth-like opening on the surface of an embryo of the archenteron in the gastrula stage.
To find an answer to the question of what is Blastopore, one must understand that a cell goes through many changes at different stages of growth and development throughout the body’s life cycle and changes and adapts according to the requirements that are demanded.
