Radiata,ive to ‘Cnidaria’, is actually synonymous with the term Radiata. Whereas Porifera are multicellular forms which function at a cellular level of organization, the radiate phyla are more advanced. These phyla function at the cell tissue level, with similar cells aggregated into definite tissues.
