Difference Between Regeneration and Fragmentation

The difference between regeneration and fragmentation is quite obvious in their respective names. Fragmentation refers to the process of splitting an organism into fragments, and each fragment grows into an organism. In contrast, regeneration is like a modified form of fragmentation and is the process of regrowth in organisms.

Definition of Regeneration

It refers to the process of renewal, restoration, and growth of tissue that makes cells, genomes, organisms, and ecosystems resilient to natural events that result in disturbances. Furthermore, every species is capable of performing regeneration, ranging from bacteria to a giant elephant. Moreover, It can either be of the complete or the incomplete type.

Definition of Fragmentation

Fragmentation refers to a form of asexual reproduction whereby a parent organism breaks into multiple fragments, each capable to form a new organism. The difference between fragmentation and regeneration is that, unlike re-generation, the whole organism gets divided into pieces in fragmentation. Furthermore, a good example of fragmentation takes place in the green algae spirogyra that floats on water.

Difference Between Fragmentation and Regeneration
Fragmentation Regeneration
Organisms that are fragmented result in each fragment growing into an individual organism It 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 some organisms can fragment and form new individuals All organisms exhibit the ability to regenerate.
It is observed in organisms such as flatworms and sponges Examples include regrowing a lost limb, such as the tail of a lizard.
