Diploblastic: 1. Body wall develops from two embryonic germ layers- ectoderm and endoderms and persists as such in adult. 2. Non- cellular, gelatinous mesogloea is present in between ectoderm and endoderm. 3. Coelom is absent, e.g. Hydra (coelenterates), sponges (Porifera). Triploblastic: 1. Body...
