Answers (1)

  • Regeneration is the process in which an organism is cut into several parts and develop into new individuals from each piece.
  • It takes place is the organisms with well-differentiated cells such as Hydra and Planaria.
  • Regeneration takes place through a specialized cell that helps in the proliferation or growth of a large number of new cells.
  • These cells later develop into cells of different types and tissue by the process of development.
  • Development is a sequence of organized steps for the conversion of undifferentiated cells into differentiated cells.
  • Regeneration is not a dependable mode of reproduction since the organism cannot wait to get cut into pieces.
