The difference between Fragmentation and regeneration is clear in their names. Fragmentation occurs when an organism completely separates itself. The broken pieces of an organism grow as independent individual organisms.
Regeneration, on the other hand, is a form of asexual reproduction in which an organism can regrow its body parts when it loses them, just as octopuses can regrow their arms when a predator bites them.
What is Regeneration?
Regeneration is the partial or complete regrowth of tissues in an organism that has suffered minor damage. This means that if an organism is divided or broken into several parts, each of its parts grows back to its original state.
Some organizations have specialized cells responsible for this process. A classic example of the regeneration process is house locusts, which shed their tails and grow back.
What is Fragmentation?
Fission A form of asexual reproduction in which an organism divides into many parts or small parts of itself. Each episode results in the growth of different, individual and independent organisms that are clones of the parent organism.
Fragmentation is the result of an organism detaching from itself, it is exhibited in some plants, fungi, starfish and annelid worms.
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 | Lizards can regenerate their amputated tails |
