Explain the process of regeneration in Planaria.
Draw diagrams to explain the regeneration that takes place in each of the body parts of planaria when its body is out into pieces. Name any other organism in which a similar process can be observed.
उत्तर
Planaria is a type of flatworm. It has the amazing capacity to regenerate its lost body part. When the flatworm is cut horizontally, separating the head from the tail, the tail will regenerate the lost head and the head will regenerate the lost tail. This process is known as regeneration. The diagram illustrating the process of regeneration in Planaria is given below.
Regeneration is one of the methods of asexual reproduction, which can be observed in Hydra also.
