Regeneration in
sponges, Paramecia, Planaria, etc.

| Introduction
Certain invertebrate
aquatic animals are able to regenerate their missing
parts. This regeneration ability in some animals is so
strong that if you cut the animal in half, each half
will grow to a complete animal. The body half
regenerates a new head and the head half regenerates a
new body.
This unusual ability is
also a method of asexual reproduction for such animals.

 |
Regeneration abilities vary
among these animals; however, they are all subject of attention
by scientists who are trying to identify the genes responsible
for such regeneration.

Project
description
In this project you will perform experiments
to observe the regeneration ability of these animals. You may
either select sponges or planarians for your experiments because
these two are visible to the naked eye and you do not have to
use a microscope and complex tools for your observations. You
may also try to study the effects of one environmental factor
such as temperature or pH on the rate of regeneration.
While gathering information
about this project, you may also learn about unusual properties
of paramecia related to regeneration, but you will not perform
any experiments with them.
