Blastopore is the pore of :During gastrulation, cells move inward (invagination), forming a new cavity called the archenteron (primitive gut).
The opening of the archenteron to the outside is the blastopore. (It becomes the mouth in protostomes and the anus in deuterostomes.)
The blastocoel is the cavity of the blastula, which gets obliterated during gastrulation.
So the blastopore is the pore of the archenteron.
