Q. Can you think of reasons why more complex organisms cannot give rise to new individuals through regeneration?

 

Answer:- 

Regeneration happens through mitosis and a particular type of tissue can give rise to its own kind only. In complex organisms, different tissues and organs have altogether different structures. Regenerating a different kind of tissue from another kind is not possible. Hence, complex organisms are unable to give rise to new individuals through regeneration.
