Abstract:
Regeneration of Planarians is the topic that will be explored and experimented. This experiment aims to prove that, flatworms placed into a warm environment will regenerate faster than flatworms in a cold environment because cold temperatures reduce metabolic rates which will slow the regeneration process. In order to prove this hypothesis flatworms were cut in half to induce regeneration. These flatworms were then separated into two containers, one was placed into a refrigerator and the other was kept at room temperature. At the end of our experiment we found that cold temperatures indeed not only slowed the regeneration in flatworms but also reduced how active they were. Both of these are good signs that the metabolism in the subjects had been reduced, thus proving our hypothesis.

Planarians belong to the animal kingdom, they are more commonly referred to as flatworms. They tend to live in streams or bodies of freshwater that are …show more content…
These animals reproduce asexually. When it is time to reproduce, a Planarian will separate itself into two halves. From these two halves, the Planarian can regenerate the lost half. For example, separated head should regenerate a new tail, while the segmented tail regenerates a new head. Charles Manor Child and Thomas Hunt Morgan, two early researchers in the field of developmental biology, performed many tests on planarians to further understanding of how these types of regeneration occur. During their trials, Child and Morgan were able to determine many factors that play a role in the success or failure of regeneration in flatworms. Their main goal, however, was to find how the organisms encode the information that specifies what part should be regenerated. Even with their extensive research we still don’t have an exact answer to
