This is an experiment on how planaria regenerate body parts and an explaination as to how the experiment was performed.

Abstract This experiment was undertaken to evaluate the varying degrees and limitations of regeneration using flatworms. Regeneration occurs in many levels throughout the animal kingdom. The flatworms demonstrated substantial healing abilities once the surgery had been performed. Total regeneration and reproduction had occurred resulting in three separate flatworms from one that had been cut through three quarters of the length of the body. Introduction Planaria belong to the phylum Platyhelminthes (flatworms). They are free-living, flat …
