The cells take in the particles through phagocytosis and then digest them, expelling wastes. Hence, major difference is that in sponges food is digested internally , but in cnidarians food is digest outside of body. The choanocytes and the amoebocytes that are present in the canal system of the sponge helps in intracellular digestion where food particles are digested inside the cellular food vacuoles by means of various acidic and alkaline enzymes.
