  1. Sponges : digestive ( collar cells and amoebocytes)  excretory (each cell gets rid of their waste by themselves) Reproductive ( gemmules and budding).

    Cnidarians: Gastrovascular cavity, budding and sexual reproduction, same as sponges for excretory.

    Worms: mouth intestine and a**s, nephridia and lateral canals, sexual reproduction and regeneration.
