WebThe choanocytes are arranged in such a way that their collars are oriented towards the apopyles. The flagella of the choanocytes are flexible with slight stiffness at the base. As a result the flagella beat from base to tip creating a water current in the same direction and drive the water from the flagellated chambers to the spongocoel. WebCorrect option is D) Spongocoel is a large central cavity in the sponges. Water enters through the numerous ostium in the cavity and exit by a central pore known as osculum. Choanocytes are the flagellated cells which line the spongocoel. It helps to set up water current and helps in intake of food.
