Carbon dioxide and other wastes, such as ammonia, diffuse into the water and are carried away.īecause they are attached, they are called sessile. Oxygen dissolved in the water diffuses into the surrounding cells.

Sponges rely on movement of water through their bodies to carry out body functions. What role does the movement of water play in the essential functions of a sponge? The structure of a choanocyte is critical to its function, which is to generate a directed water current through the sponge and to trap and ingest microscopic food particles by phagocytosis. The feeding chambers inside the sponge are lined by choanocytes (“collar cells”). Why is movement of water through a sponge important for feeding How are Choanocytes involved in this process?
