WebChoanocytes line is the inner portions of spaces in the sponges that allow the flow of water. The water current is maintained through the presence of flagella so that food particles … 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. pods baton rouge
