Are Mollusks segmented worms and arthropods Protostomes?
Yes, molluscs fit into the group known as protostomes.
What is an example of a protostome?
An example of a protostome is a snail. Protostomes are organisms in which the blastopore, the opening of the developing embryo, becomes the mouth of the adult organism.
Are flatworms prokaryote or eukaryote?
They are protostomes.
What are the three phyla under protostomes?
The three main phyla under protostomes are Annelida (segmented worms), Mollusca (mollusks), and Arthropoda (arthropods). These organisms share a common characteristic of developing their mouths from the first opening formed during embryonic development.
Are leeches protostomes?
Yes, since they are annelids, they are protostomes.
Are bivalves protostomes or deuterostomes?
Bivalves are protostomes. They belong to the phylum Mollusca, which is characterized by protostome development. This means that during their embryonic development, the blastopore becomes the mouth.
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.
Is chaetognatha solidly advanced deuterostomes?
No, chaetognaths are not considered deuterostomes. They belong to the phylum Chaetognatha (arrow worms), which are classified as protostomes. They are characterized by certain developmental and anatomical features that distinguish them from deuterostomes.
What characteristics of a segmented worm make it a worm?
Annelids are bilaterally symmetric and triploblastic protostomes with a coelom, closed circulatory system and true segmentation. Their segmented bodies and coelom have given them evolutionary advantages over other worms.
Are mammalia deuterostomes?
Deuterostomes. All chordates such as birds and mammals are deuterosomes.
Are bivalves protosomes or deuterostomes?
Protostomes .
What is the animal if the blastopore develops into a mouth?
protostomes:)
