Members of this phylum can reproduce by releasing masses of amoeboid cells called gemmules.
Members of this phylum can reproduce by releasing masses of amoeboid cells called gemmules. Some members of this phylum create circulating water currents using cells with flagella that trap and filter food with microvilli. In addition to possessing choanocyte cells, some members of this phylum have sycon and leucon body forms. These organisms absorb water through an opening called the osculum, and they possess a skeleton made from spicules. Members of this phylum possess a jelly-like layer in the interior called mesohyl, but they lack tissues and organs. Less complex than cnidarians, for 10 points, name this simplest animal phylum, which contains the sponges.
