collar cell การใช้

Such a flow rate allows easy food capture by the collar cells.
Among animals, collar cells ), they lack true tissue coordination.
One possible scenario inspired by the proposed hypothesis starts with the idea that the monociliated cells of the epitheloid in " Trichoplax adhaerens " evolved by reduction of the collars in the collar cells ( choanocytes ) of sponges as the ancestors of the Placozoa abandoned a filtering mode of life.
Perhaps the best-known holozoans, apart from animals, are the choanoflagellates, which strongly resemble the collar cells of sponges, and so were theorized to be related to sponges even in the 19th century . " Proterospongia " is an example of a colonial choanoflagellate that may shed light on the origin of sponges.
