WebWater enters the sponge through a series of incurrent canals and passes through internal pores called prosopyles into the radial canals, which are lined with flagellated collar cells known as choanocytes. It is the action of these choanocytes that keeps water moving through the sponge. 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 feeding chambers inside the sponge are lined by choanocytes ("collar cells"). 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 … WebThe choanoflagellates are _____. 1. eukaryotic organisms. 2. organisms that resemble the feeding structures of sponges. 3. organisms that have cells with a flagellum surrounded by a collar. Scientists are investigating the possibility that the _____ and metazoans might share a common ancestor due to the presence of homologous proteins. 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. golden beach chinese restaurant menu
