Essay about planaria regeneration

In sexual reproduction each Planaria gives and receives sperm. Planaria have both testes and ovaries. Eggs develop inside the body and are shed in capsules. Weeks later the eggs hatch and grow into adults. Planarians can also reproduce by regeneration. If a Planaria is cut into two halves, both halves may become two new Planaria (regeneration).

Planarians: performing artists of nervous system regeneration. Owing to the presence of chemo-, mechano- and light-sensory neurons that are assembled with others into a CNS, planarians react rapidly to environmental conditions, contact and light (reviewed in Cebrià, 2007; Agata and Umesono, 2008). Classical and instrumental conditioning in Planaria ... Download file to see previous pages, processes for developing classical and instrumental conditioning training techniques in planaria and California Black Worms are examined in order to study the memory mechanism in the organism. This is an experiment on how planaria regenerate body parts ... Planaria belong to the phylum Platyhelminthes (flatworms). They are free-living, flat bodied, freshwater animals that demonstrate the notable ability to regenerate their lost body parts. "In some genera, when a single individual is divided into two or more parts, each part can regenerate an entirely new flatworm" (Johnson).
