lend them their regenerative qualities . Planarians reproduce A-sexually so they can basically clone themselves ‚ Because they reproduce A-sexually planaria and their genomes can be created over and over again . Planarians are tiny flatworms that live in freshwater and marine environments and on plants all over the world . the cells that are in planaria are ready to transform into whatever tissue the planarian needs to regenerate their simple bodies and few tissues make planarians easy

Animal Phyla Lab Adapted from “Phylum Lab” produced by the National Aquarium in Baltimore The diversity of animal life on Earth is astounding. Each animal has a unique body plan which allows it to survive and adapt to its given surroundings. With such an abundance of species‚ classifying animals into different categories is necessary. At first the diversity of animals can be overwhelming‚ but after further research and observation‚ many likenesses appear. These similarities become the basis for

10/20/2014 Background: The planarian‚ also known as the flatworm‚ is a creature that live all over land‚ oceans‚ and freshwater. (Biggs‚ A.‚ Gregg‚ K.‚ Hagins‚ W.‚ Kapicka‚ C.‚ Lundgren‚ L.‚ Rillero‚ P.‚ 2002) The planarian has a threebranched digestive cavity. (Alvarado‚ 2004) Planaria range from 1/8 to 1 inch. (Alvarado‚ 2004) The planarian can be cut into many pieces and each piece will grow into a new flatworm. (Alvarado‚ 2004) Planaria produce asexually‚ therefore the planarian pretty

A planarian is free-living flatworm that lives in fresh water. Planarians are organisms that live in freshwater. Planarians are part of the metazoan phylum. Animals in the metazoan like jellyfish have the ability to regenerate (Raymond 511-512). Planarians are closely related to animals like jellyfish and starfish. These animals shared the same special ability to regenerate; starfish are able to regenerate their arm when it is cut off. Jellyfish are able to regenerate their stinger when cut off (Li
