Choanocytes are special cells ... 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.

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. WebThe cumulative effect of the flagella from all choanocytes aids the movement of water through the sponge: drawing water into the sponge through the numerous ostia, into the spaces lined by choanocytes, and eventually out through the osculum (or osculi).
