Scale bars indicate 50 µm (1), 25 µm (2, 4–6), 10 µm (3).Six images. The coverslip print has disintegrated the sponge, making the amoeboid, totipotent cells visible. Totipotent means embryonic in the sense that each of these cells is capable of developing into a new sponge through successive mitotic divisions.
