| • Porifera |
o capture food particles in the water that passes their their body.
o Water is drawn through the pores into a central cavity, the spongocoel and then flows out of the sponge through a larger opening called the osculum
o lack true tissues meaning they have groups of similar cells that act as functional unit and are isolated from other tissue by membranous layers. |
