Answer:
Difference Between Fragmentation and Regeneration
Regeneration is termed as an asexual mode of reproduction. It is common in unicellular organisms and lower multicellular organisms, such as planaria. Here, the organism fragments when it’s ready to reproduce, and new organisms are regenerated from these fragmented parts. The difference between regeneration and fragmentation are summarized below:
Difference Between Fragmentation and Regeneration
Fragmentation Regeneration
Organisms that are fragmented result in each fragment growing into an individual organism Regeneration occurs when an organism only regrows a lost limb or any other part of the body.
A new individual emerges from each fragment No new organisms are formed
Only a few organisms can fragment and form new individuals All organisms exhibit the ability to regenerate (Only to some degree)
Fragmentation is observed in organisms such as flatworms and sponges Examples of regeneration include regrowing a lost limb, such as the tail of a lizard. (Please note: Most lizards can lose their tails and then have them grow back. But if they lose their forelimb or hindlimb, it will not regrow)
