What is protostome embryonic development?
In protostomes, the blastopore develops into the mouth, and the anus develops from an opening later in development. In deuterostomes, the blastopore develops into the anus, and the mouth develops secondarily. Mesoderm and coelom formation are intimately tied together during development.
What are the two distinguishing features of protostome embryonic development?
What are the two distinguishing features of protostome embryonic development? B is correct. During embryonic development, protostomes display spiral cleavage, and during gastrulation, the blastopore develops into the mouth.
What is the difference between protostome and deuterostome development?
Protostome and deuterostome are terms for members of major taxonomic groups of animals categorized by how they develop as embryos. In protostomes, the first opening in the embryo becomes the mouth. In deuterostomes, the first opening in the embryo becomes the anus, and the mouth develops later.
What are the main differences between protostomes and deuterostomes?
Main Difference – Protostomes vs Deuterostomes
The main difference between protostomes and deuterostomes is that in protostomes, the blastopore is developed into the mouth whereas in deuterostomes, the blastopore is developed into the anal opening. Both Protostomia and Deuterostomia forms the clade: Nephrozoa.
What are the 3 differences between deuterostomes and protostomes?
What are three differences in the developmental patterns of protostomes and deuterostomes?
The main difference between protostomes and deuterostomes is that the blastopore in protostomes are developed into a mouth while the blastopore in deuterostomes is developed into an anal opening.

| Protostomes | Deuterostomes |

| It exhibits determinate cleavage | It exhibits indeterminate cleavage |
What are the main characteristics of protostomes and deuterostomes?
The main defining trait in protostomes is that the mouth develops before the anus. In humans, the anus develops before the mouth which makes it a deuterostome. Deuterostomes are animals in which the anus develops before the mouth during the embryonic stage.
What is a major difference between protostomes and deuterostomes during early development?
The main difference between protostomes and deuterostomes is that in protostomes, the blastopore is developed into the mouth whereas in deuterostomes, the blastopore is developed into the anal opening. Both Protostomia and Deuterostomia forms the clade: Nephrozoa.
What are the major differences between protostome and deuterostome development?
What is the most notable difference regarding embryonic development between protostomes and deuterostomes?
Both protostomia and deuterostomia also consist of differences in the development of their three germ layers. Deuterostomes bear a higher modified nervous and muscular systems. The key difference between protostomes and deuterostomes is thus the fate of blastopore in their embryonic development.
What are the three main characteristics of protostomes?
The protostomes are a large and diverse group, classified by their shared characteristics. These include having true tissues, being bilaterally symmetric, and developing the mouth before the anus during embryonic development.
What is the major difference between protostomes and deuterostomes?
The most significant difference between protostomes and deuterostomes arises due to the dissimilarities in their embryonic development. In protostomes, the blastopore forms in the mouth, but in deuterostomes, the blastopore is involved in the development of the anus.
