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.
Annelids are the first of the animal phyla studied to have what general characteristic?
Annelids are the first animal phyla to have a true body cavity (coelom), which is enclosed by mesoderm. This cavity enables more complex organ systems and allows for greater specialization of body functions.
What acoelomate Phyla?
The acoelomate phyla are Platyhelminthes (flatworms) and Nemertea (ribbon worms). These animals lack a true body cavity (coelom) between their digestive tract and body wall. Acoelomates rely on other means, like a simple body plan and mesenchyme tissue, for support and structure.
Which of the animal phyla was the first to evolve three germ layers?
The first animal phylum to evolve three germ layers was the Cnidaria. These germ layers are the ectoderm, endoderm, and mesoderm, found in more complex animals for the development of different structures and organs.
What is the plural form of the word phylum?
The plural form of phylum is phyla.
What is a protostome?
This is straight from dictionary.com, so no credit for me: "any member of the lower invertebrate phyla in which the mouth appears before the anus during development, cleavage is spiral and determinate, and the coelom forms as a splitting of the mesoderm." That help? :)

Are cnidarians protostomes or deuterostomes?
Although most of the animal phyla are included in the deuterostomes and protostomes, cnidaria, porifera, placozoa and ctenophora are not included in the group of animals know as Bilateria (which contains the deuterostomes and protostomes). Cnidarians and ctenophores are in a group called Radiata, and Porifera and Placozoa are in the group known as Parazoa.
Do arthropod have coelom?
Yes, phylum Arthropoda is classified as coelomate along with about half of all known phyla, including molluscs, annelids, and chordates.
Do genera populations phyla kingdoms or individuals evolve?
Individuals evolve through natural selection, leading to changes in the characteristics of populations over time. These changes can eventually lead to the evolution of new species within a specific genus, which may contribute to the diversification of higher taxonomic groups such as phyla and kingdoms.
What is a prostodome?
Protostome: any member of the lower invertebrate phyla in which the mouth appears before the anus during development, cleavage is spiral and determinate, and the coelom forms as a splitting of the mesoderm.
