WebChoanocytes These distinctive cells line the interior body walls of sponges. These cells have a central flagellum that is surrounded by a collar of microvilli. choanoflagellatesthat make many scientists believe that choanoflagellates are the sister group to Choanocytes are versatile cells. WebChoanocytes of another sponge trap sperm and retain it in a vacuole. The choanocyte then looses its collar and flagellum. The cell is now called a carrier cell. This cell migrates through the mesohyl to an ovum. The carrier cell enters the cytoplasm of the ovum. Development of the larva takes place within the parent sponge.

There is also evidence of historical mating and recombination in S. rosetta. S. rosetta is induced to undergo sexual reproduction by the marine bacterium Vibrio fischeri. Choanocytes (also known as "collar cells") are cells that line the interior of asconoid, syconoid and leuconoid body types of sponges that contain a central flagellum, or cilium, surrounded by a collar of microvilli which are connected by a thin membrane. They make up the choanoderm, a type of cell … See more Choanocytes are found dotting the surface of the spongocoel in asconoid sponges and the radial canals in syconoid sponges, but they comprise entirely the chambers in leuconoid sponges. See more Choanocytes bear a superficial resemblance to Choanoflagellates. Molecular phylogenies indicate that choanoflagellates and See more By cooperatively moving their flagella, choanocytes filter particles out of the water and into the spongocoel, and out through the osculum. This improves both respiratory and digestive functions for the sponge, pulling in oxygen and nutrients and allowing a … See more • Choanocytes See more

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.
