What is Regeneration?

Regeneration is asexual reproduction is the ability of a simple organism to re-grow its lost parts.

Simple organisms are more successful with regeneration than complex organisms. For example, some crabs can grow new claws or body parts after the original parts are lost. Regeneration of lost body parts occurs mostly in invertebrates. Note that the broken off claw may not be able to grow into a new lobster.

Some lizards (such as the leopard gecko) can grow new tails when they lose them (autotomy).

Regeneration in asexual reproduction

One great example of regeneration in living organisms is the Planarium, a type of flatwork which scientists love to study. If this flatwork is cut into two with a razor, the head will regrow a new tail and the tail will regrow a new head in just a couple of weeks.

NB: The flatworm is also a great example of fragmentation asexual reproduction as discussed in the next page.
