How do sponges digest food? These cells then pass the nutrients to other cells. Sponges achieve the goal of digestion through intracellular digestion where food particles are digested inside specialized cells. Amoebocytes transport nutrients within the layers of the sponge. The enzymes catalyze the digestion of the food into molecules small enough to be taken up by passive diffusion, transport, osmotrophy or phagocytosis.Since digestion occurs outside the cell, it is said to be extracellular.
