FRAGMENTATION
In cell biology, fragmentation is the breaking apart of cells or cell organelles into smaller parts. Fragmentation may serve as a normal function for the cell, but may also be the result of a disorder.
REGENERATION
In biology, regeneration is the process of renewal, restoration, and growth that makes genomes, cells, organs, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage. Every species is capable of regeneration, from bacteria to humans.[1][2] At its most elementary level, regeneration is mediated by the molecular processes of DNA synthesis.

Fragmentation is a form of asexual reproduction where an organism is split into fragments. The splitting may or may not be intentional. Each of these fragments develop into mature, fully grown individuals that are a clone of the original organism. If the organism is split any further the process is repeated. Fragmentation is caused by mitosis. Meiosis is not involved in fragmentation.
Fragmentation is seen in many organisms such as molds some annelids worms, and sea star binary fission of single-celled organisms such bacteria , protozoa and many algae is a type of fragmentation.Molds, yeast, and mushrooms, all of which are part of the Fungi kingdom, produce tiny filaments called hyphae. These hyphae obtain food and nutrients from the body of other organisms to grow and fertilize. Then a piece of hyphae breaks off and grows into a new individual and the cycle continues.
Fragmentation is observed in nonvascular plants as well, liverworts and mosses
Regeneration is the ability of a living organism to regrow a portion of its body that has been injured or lost. Plants may regenerate stems, leaves, and flowers so long as their roots have not been destroyed. Some animals with simple body plans, such as the hydra polyp and flatworm, can regenerate a complete body from small fragments of themselves. Crabs can replace severed legs. Mammals can regenerate liver cells and blood cells; other specialized cells are replaced with scar tissue that does not regain the function of the lost or damaged tissue ....
Hope u got thisss!!!!!!

Worms such as ribbon-worms (Nemertinea) and flatworms (Turbellaria).
Fragmentation takes places in hydra, planaria and sponges. The fragments regenerate to form an entire individual.
Regeneration
Regeneration is one of the methods of asexual reproduction in lower or less evolved animals. When the parent body breaks into pieces, each piece can grow into a new organism.

Hi,
Both regeneration and fragmentation are the type of asexual reproduction. They both stands for the same meaning i.e growth of an organism from a part of the body. Regeneration is mainly associated with the animals whereas fragmentation is mainly associated with the plants.
Fragmentation is also a mode of asexual reproduction. It is the unintentional cutting up of the body of an organism which each grows into different organism. It is most commonly seen in some algae.
Hope this answers your query

Renegeration is the growing back of a lost part of the body of an organism. It is usually used as a method of defence. it cnnt be settled uder reproduction....
Fragmentation...u cn sayy..is an unintentional cutting up .... of . .. the .... body of an organism which each grows into different organism. It'zz....a mode of asexual reproduction.....
For example, a lizard can intentionally leave itzz.. tail behind n grow it back later on. But the tail cannot grow into a lizard. While growing the tail back means that it can regenerate from the point where it was cut off, the tail not growing into a lizard means that it can't fragment itself to reproduce.....morovrr...
Fragmentation is true for lower multicellular organisms which have cellular level of organisation...lik spyrogyra..wenn it bcums too large it break.....
On the other hand Regeneration is for higher mmulticellular organism who have tissue level of organisation EG: PLANERIA
hope this helps..!!!:))
