Answer :
Answer:
Explanation:
The key difference between protostomes and deuterostomes is the fate of the blastopore during their embryonic development. The blastopore in a protostome develops into a mouth, where as the blastopore in deuterostomes develops into an (a n a l) opening.
Protostome- Blastopore develops into a mouth. Spiral, determinate cleavage. Schizocoelous formation of the coelom. Annelids, mollusks, and arthropods
Deuterostome- Blastopore develops into an anus. Indeterminate cleavage. Radial cleavage pattern during early development. Echinoderms and the chordates.
Both- Distinct evolutionary lines of coelomates. Complex skeletons that allow them to be highly mobile. Bilateral symmetry. Triploblastic.
