Question
Draw diagrams to explain the regeneration that takes place in each of the body parts of planaria when its body is cut into pieces. Name any other organism in which a similar process can be observed.
Solution
The figure below shows the step-by-step process of regeneration in planaria.
Planaria has the amazing capacity to regenerate its lost body part. When it is cut horizontally, separating the head from the tail, the part with tail regenerates the lost head and the part with head regenerates the lost tail. This process is known as regeneration.
Hydra uses the method of regeneration for its propagation.
