Question

what is parazoa and eumetazoa ​

Answer 1

Answer:

Explanation:

Parazoa are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells.

Eumetazoa is a clade which includes all major animal phyla except sponges, and a few other groups of animals, such as the Placozoa. The Eumetazoa have true tissues, neurons, and an embryo that goes through a gastrula stage.

Answer 2

Answer:

Eumetazoa are animals whose tissue are organized into true tissues and there is a development of organs. Parazoa lack this tissue organization. This signifiies that eumetazoa have more complexly organized tissue than parazoa do. Examples of parazoa belong to phylum porifera, or sponges.
