The water contains all the food and oxygen they need, and they circulate the water thru their pores. Also, I dont know if this helps, but they keep food inside their bodies and from going out their pores with their collar cells that acts as little whips.

However , in sponges their cells don't perform specific duties as they can easily differentiate and begin to person other function, hence cells cannot become a structural unit(organ)
