Are Sponges Diploblasts

Does sponges are diploblastic or triploblastic?

Porifera is neither triploblastic nor diploblastic since Porifera contains the cellular level of organization. Diploblastic and Triploblastic animals are those which have a tissue level of organization.

What phylum animals are diploblastic?

Diploblastic organisms are organisms which develop from such a blastula, and include cnidaria and ctenophora, formerly grouped together in the phylum Coelenterata, but later understanding of their differences resulted in their being placed in separate phyla. The endoderm allows them to develop true tissue.
