Difference between Fragmentation and Regeneration

The difference between fragmentation and regeneration is very clear. When an organism splits off from itself, separation happens. The fragmented parts of the organism evolve into distinct individual organisms. On the other hand, regeneration is a type of asexual reproduction. It is normal in unicellular and lower multi-cellular species, like planar. In this article, we will discuss the difference between fragmentation and regeneration. But firstly, we will know about fragmentation and regeneration.

What is Fragmentation?

Fragmentation refers to the process of asexual reproduction by which the parent organism splits into multiple fragments, and each fragment is capable of forming a new organism. The distinction between fragmentation and regeneration is that, unlike regeneration, fragmentation splits the entire organism into parts. The green algae spirogyra that floats in water is a good example of fragmentation. It is also known as splitting and reproduction processes. It may be seen in various species like bacteria, filamentous cyanobacteria, lichens, sponges, flatworms, etc.

What is Regeneration?

It is the processes in which the organism is cut into many parts, and each part can return to its original state. This process is conducted by specialized cells called stem cells. It occurs in species that have a very basic structure and very few specialized cells. The cells are easily separated into a large number of cells. Each cell changes to shape in different types of cells and tissues. This sequential change process is defined as development. The tissues are formed by different sections of the body and organs.

Main differences between the fragmentation and regeneration

The following are the key differences between fragmentation and regeneration:

1. Fragmentation may occur in multi-cellular species with the body's basic organization. In contrast, regeneration may occur in a fully differentiated multi-cellular organism with a complex body organization.
2. In fragmentation, the organism splits into pieces, and each piece evolves into a new entity. Whereas in regeneration, the organisms divide into parts, and the parts may or may not be grouped into a new body.
3. Any specialized cells are not involved in fragmentation. In contrast, specialized cells proliferate and form a mass of cells in regeneration. Cells vary from mass to shape in various types of cells and tissues.

Conclusion

Fragmentation is a form of asexual reproduction in which the organism reproduces by breaking into parts, and each part grows into a particular organism. On the other hand, regeneration may occur when an organism regrows some parts or limbs that have been damaged due to predation.
