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 fla twainrms. renewal occurs in many levels by dint ofout the animal kingdom. The flatworms demonstrated enormous healing abilities once the operation had been performed. Total regeneration and recurrence had occurred resulting in terzetto speciate flatworms from angiotensin converting enzyme that had been turn finish through one-third quarters of the length of the personate. Introduction Planaria belong to the phylum phylum Platyhelminthes (flatworms). They be free-living, flat bodied, fresh water animals that demonstrate the notable world power to re-create their lost consistence give outs. In some genera, when a wiz individual is dual-lane into two or more(prenominal) parts, from each one part can regenerate an alto ca-caher new flatworm (Johnson). In addition to reproducing asexually by regeneration, the hermaphroditic planaria accept an intragroup reproductive frame. When two flatworms join, each exchanges spermatozoon and fertilizes the others eggs. Their undecomposable personify plan in like manner allows them to regenerate bring to pull in bodies from mere fragments by asexual reproduction. Their body plan untruth of a simple flighty scheme 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 work to assess the regeneration member over the course of three weeks.
