text: In one larval type (parenchymella), the flagellated outer cells become the collar cells (choanocytes) of the interior of the adult sponge; the interior cells of the larva give rise, in the adult, to the cell layer (pinacoderm) and the different cells (e.g., archaeocytes, collencytes) found in the amorphous substance (mesohyl) that fills the sponge.
