Which term describes the absence of true tissues in Porifera?

Explanation:
Absence of true tissues in Porifera is described by the term Parazoa. Sponges show cellular-level organization with specialized cell types, but they do not have true tissue layers or germ layers, so they lack the organized tissues seen in other animals. That makes Parazoa the best descriptor for Porifera. In contrast, animals with true tissues belong to Eumetazoa, the broader Metazoa encompasses all animals, and Protozoa refers to single-celled organisms not animals.
