Explanation:
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 regeneration, the whole organism gets divided into pieces in fragmentation. Furthermore, a good example of fragmentation takes place in the green alga (algae) spirogyra that floats on water.
Definition of Regeneration
Regeneration 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 specie is capable of performing regeneration, ranging from the bacteria to a giant elephant. Moreover, regeneration can either be of the complete or the incomplete type
Answer:
Fragmentation and regeneration are two completely different processes. Fragmentation is one of the types of asexual reproduction whereas regeneration is the regrowth of a tissue in an organism. Let’s have a look at the differences between fragmentation and regeneration.
Fragmentation
Regeneration
Fragmentation is one of the types of asexual reproduction.
Regeneration is not a form of sexual or asexual reproduction.
In fragmentation, the body of an organism breaks into fragments. Every fragmented part of the body grows into an individual separate organism.
In regeneration, partial or complete regrowth of the tissue takes place.
The process of fragmentation gives rise to new individual organisms.
The process of regeneration does not give rise to new individual organisms.
Fragmentation is mostly seen in organisms with a simple body organization.
Regeneration is mostly seen in organisms with a complex body organization.
Fragmentation is not seen in all animals. It is specific to a few particular species only.
Regeneration is seen in all multicellular organisms having a complex body organization.
There’s no involvement of specialized cells in the process of fragmentation.
The process of regeneration involves the use of some specialized cells. These specialized cells proliferate and form clusters. The cells present in the cluster further undergo proliferation to form new cells.
The process of fragmentation is observed only in invertebrate species.
The process of regeneration is observed in vertebrate and invertebrate species as well.
Fragmentation is mostly observed in non-vascular plants.
Regeneration is mostly observed in animals.
The fragmentation process is largely associated with the structural complexity of an organism. Fragmentation is quite common in organisms with a simple body organization.
Regeneration is not associated or dependent on the structural complexity of an organism. Irrespective of class & category, regeneration is observed in almost all multicellular living organisms.
The fragmentation process is triggered either in the presence of a predator or as a result of a natural process.
The regeneration process is triggered by the damaged body part.
Example: Fragmentation is seen in organisms such as flatworms, sponges, and sea anemones.
Example: The regeneration of the partly or completely cut lizard tail is the best example for regeneration.
Similarly, regrowth of blood vessels and regrowth of octopus limbs are the other examples of this phenomeno
