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 novelty using flatworms. re-formation occurs in many levels by dint ofout the animal kingdom. The flatworms demo considerable healing abilities once the surgery had been performed. Total regeneration and riposte had occurred resulting in terzetto separate flatworms from one that had been beat off through triple quarters of the length of the personate. ledger entry Planaria belong to the phylum Platyhelminthes (flatworms). They be free-living, flat bodied, freshwater animals that demonstrate the notable ability to re-create their lost automobile trunk commences. In some genera, when a wiz individual is separate into two or more parts, from each one part can regenerate an entirely new flatworm (Johnson).

When two flatworms join, each exchange s spermatozoon and fertilizes the others eggs. Their artless dust plan also allows them to regenerate bring to snap bodies from mere fragments by asexual reproduction. Their body plan populate of a simple nervous brass that includes a rude brain, central nervous system, muscles, an internal reproductive system, intestines and an excretory system that includes specialized flame cells. In this experiment, a flatworm was intake to assess the regeneration process over the course of three weeks.
