What else can I help you with?
Name at least one phylum example of each protostomes and deuterostomes?
Protostome example: Arthropoda (insects, spiders) Deuterostome example: Chordata (vertebrates, including mammals, birds, and fish)
What does the blastopore become?
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
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.
Are nematodes protostomes or deuterostomes?
Nematodes are protostomes. They belong to the Ecdysozoa group within the larger protostome clade, characterized by their molting of a cuticle as they grow. This distinguishes them from deuterostomes, which include organisms like chordates and echinoderms, where the embryonic development follows a different pattern.
Are the phylums Ctenophora or Platyhelminthes protostome or deuterostonme?
"They are neither. This is because they do not have a true gut. Protostomes are annelidids(earthworms) Mollusca(clams, snails, octopus, etc.) and arthropods which are your insects or spiders. The only Deuterostomes are Phlya Chordota and Echinodermata." The above answer is incorrect. Plathyhelminthes are protostomes. There are many, MANY groups of protostomes besides annelids, molluscs, and arthropods.
Coelomates that develop with the blastopore becoming the mouth are?
Coelomates that develop with the blastopore becoming the mouth are protostomes. An example of a protostome would be the Caribbean reef squid.
What is the difference of a protostome animal and dueterostome animal?
the difference is that a duetrostome (second mouth) is the end and the protostome(first mouth) is the begining.
Pigeons deuterostome or protostome?
deuterostomes
Is a grasshopper a deuterostome or a protostome?
protosome
Name at least one phylum example of each protostomes and deuterostomes?
Protostome example: Arthropoda (insects, spiders) Deuterostome example: Chordata (vertebrates, including mammals, birds, and fish)
Are annelida protostome?
Yes, annelids belong to the protostome group of animals. Protostomes are a group of animals whose blastopore develops into the mouth first during embryonic development. Annelids, such as earthworms and leeches, exhibit characteristics consistent with protostome development.
What is the synapomorphy of the Ecdysozoa plus Lophotrochozoa clade?
protostome development
What are the key differences between deuterostome and protostome development processes?
Deuterostome and protostome are two different ways in which animals develop. In deuterostome development, the first opening that forms becomes the anus, while in protostome development, the first opening becomes the mouth. This difference in the formation of the digestive tract is a key distinction between the two processes.
At which developmental stage should I be able to distinguish a protostome embryo from a deuterostome embryo?
Gastrulation
What happens to the coelom as each phyla of protostomes evolve?
As protostome phyla evolve, the coelom may change in structure and function. For example, in some phyla like annelids, the coelom functions as a hydrostatic skeleton. In arthropods, the coelom may be reduced or lost altogether.
What does proto and deutero?
Protostome means the blastopore becomes the mouth during embryonic development, and deuterostome, the anus. We're deuterostomes.
What are the key differences between protostome and deuterostome development processes?
Protostome development involves the blastopore forming the mouth first, while deuterostome development involves the blastopore forming the anus first. This difference in embryonic development leads to distinct patterns of cell division and fate determination in these two groups of animals.
