Simple organisms like Hydra and Planaria can produce a new individual through the process of regeneration. However, In a complex multicellular organism have an organ-system level of organisation. Each organ systems of their body work together as an interconnected unit.

They have a high degree of organisation in their body. So, they cant be reproduced from their cut body parts by the regeneration process.
