The bubble algae (Valonia ventricosa) is actually a single-cell organism and it reproduces by sending out rizomes like Caulerpa (which is also a single-cell organism) or division where it sends out split off daughter cells.Producing spores would happen in the same way as when Caulerpa "goes sexual" and involve the … This includes Valonia ventricosa, which can be up to 5 cm in length.
