Question

Give an example for each of the following
categories (acoelomate)​

Answer 1

Answer:

An acoelomate is an animal which lack a coelom, or formal body cavity. True body cavities form only in multicellular organisms with true tissues. Within this group, the eumetazoa, there are the organisms like coral and jellyfish, which have only 2 basic tissues. The triploblastic eumetazoa have 3 tissue types.

An acoelomate is the simplest form of animals which have 3 true tissues. These tissue are the endoderm, mesoderm, and ectoderm, in that order from inside to out. In an acoelomate, these tissues touch back-to-back, without any space in between. The organs form within it, and are surrounded by the mesoderm. The ectoderm is the skin, while endoderm forms the digestive tract.
