Specific excretory organs are absent in unicellular organisms belonging to the<u> phylum Porifera.</u>

The organisms of the phylum Porifera are classified under the kingdom Animalia and they lack specific organs in their bodies.

Moreover, in them, reproduction takes place through fragmentation and budding.
