Do phylum porifera have organs and true tissues?

No, phylum Porifera, which includes sponges, do not have true tissues or organs. Instead, they are composed of a simple aggregation of cells, with a porous structure that allows water to flow through. Their cells perform various functions, but they lack the complex organization found in more advanced animal phyla. Instead, they rely on the movement of water for feeding, respiration, and waste removal.
