At the stage of development when the gut forms there is only a single opening into the digestive track, this opening may become either the mouth or anus. In the echinoderms, chordates, and hemichordates the blastopore becomes the anus and a new opening forms the mouth, these are called deuterostomes

Is a jellyfish a blastopore?
No.
The structure that is found in an opening to the central cavity and develops into a mouth or an anus in the organism is called the?
blastopore.
What is deuterostome development?
The mouth is formed second, after the anus.
What is a blastopore and how is it used to indicate evolutionary relationship?
It's a cavity that becomes the mouth and anus. Depending on which forms first, the animal is classified as a protostome (first mouth) or deutrosome (second mouth). This shows a relationship among very differed looking animals.
Does the sun eventually become a neutron star?
As far as we know, the sun will never become a neutron star. it will eventually become a Red Giant and then it will eventually become a white dwarf
What is a blastopore?
A blastopore is a term for the opening into the archenteron in embryology.
Is a jellyfish a blastopore?
No.
The structure that is found in an opening to the central cavity and develops into a mouth or an anus in the organism is called the?
blastopore.
Does the blastopore forms a mouth?
In protostome ("first mouth") the blastopore, or the first opening formed becomes the mouth. In deuterostomes ("second mouth"), the blastopore forms the anus and the mouth develops from a second opening.
Why is gastropore a more correct term than blastopore?
because the blastopore develops at gastrula stage not blastula. so it is supposed to be gastropore.
What is the opening outside of the gastrula called?
blastopore
What is meant by blastopore fate?
fock u
What is the animal if the blastopore develops into a mouth?
protostomes:)
An animal with an anus that develops from or near the blastopore?
Its a deuterostome
Are Chordates and echinoderms are both protostomes?
Neither are protostomes. Chordates, Hemichordates, and Echinoderms are all deuterostomes (in that the blastopore forms the anus first). In protostomes, the blastopore forms the mouth first.
How is a blastopore used to indicate evolutionary relationships?
The blastopore is an indentation that forms during early embryonic development. Its fate can differ between species, with some having the blastopore develop into the mouth (protostomes) and others into the anus (deuterostomes). This distinction is used to infer evolutionary relationships between organisms, as species that share similar blastopore fates are considered more closely related.
The blastopore is a structure that first becomes evident during?
gastrulation
