Fragmentation in multicellular organisms is a form of asexual reproduction in which an organism is split into fragments.
Each of these fragments develop into matured, fully
Describe fragmentation in asexual reproduction the offspring individuals that are identical to their parents. The splitting may or may not be intentional — it may or may not occur due to man-made or natural damage by the environment or predators. This kind of organism may develop specific organs or zones that may be shed or easily broken off.
If the splitting occurs without the Describe fragmentation in asexual reproduction the offspring preparation of Describe fragmentation in asexual reproduction the offspring organism, both fragments must be able to regenerate the complete organism for it to function as reproduction.
Fragmentation, also known as splitting, as a method of reproduction is seen in many organisms such as filamentous cyanobacteriamoldslichensmany plants, and animals such as spongesacoel flatwormssome annelid worms and sea stars.
Moulds, yeasts and mushroomsall of which are part of the Fungi kingdomproduce 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. Many lichens produce specialized structures that can easily break away and disperse.
These structures contain both the hyphae of the mycobiont and the algae phycobiont see soredia and isidia. Larger fragments of the thallus may break away when the lichen dries or due to mechanical disturbances see the section on reproduction in lichens.
Fragmentation is a very common type of vegetative reproduction in plants. Many treesshrubsnonwoody perennialsand ferns form clonal colonies by producing new rooted shoots by rhizomes or stolonswhich increases the diameter of the colony. If a rooted shoot becomes detached from the colony, then fragmentation has occurred. There are several other mechanisms of natural fragmentation in plants.
People use fragmentation to artificially propagate many plants via divisionlayeringcuttingsgraftingmicropropagation and storage organssuch Describe fragmentation in asexual reproduction the offspring bulbscormstubers and rhizomes.
Animals like sponges and coral colonies naturally fragment and reproduce. Many species of annelids and flat worms reproduce by this method. When the splitting occurs due to specific developmental changes, the terms architomy, paratomy and budding are used. In architomy the animal splits at a particular point and the two fragments regenerate the missing organs and tissues. The splitting is not preceded by the development of the tissues to be lost.
Prior to splitting, the animal may develop furrows at the zone of splitting. The headless fragment has to regenerate a complete head. In Describe fragmentation in asexual reproduction the offspring Describe fragmentation in asexual reproduction the offspring occurs perpendicular to the antero-posterior axis and Describe fragmentation in asexual reproduction the offspring split is preceded by the "pregeneration" of the anterior structures in the posterior portion.
The two Describe fragmentation in reproduction the offspring have their body axis aligned i. Budding can be considered to be similar to paratomy except that the body axes need not be aligned: Convolutriloba retrogemma an acoel flat worm. Many types of coral colonies can increase in number by fragmentation that occurs naturally  or artificially. Within the reef aquarium hobby, enthusiasts regularly fragment corals for a multitude of purposes including shape control; selling trading with, or sharing with others; regrowth experiments; and minimizing damage to natural coral reefs.
Both hard and soft corals can be Genera that have shown to be highly tolerant of fragmentation include AcroporaMontiporaPocilloporaEuphylliaand Caulastraea among many Describe fragmentation in asexual reproduction the offspring. There are a variety of methods including longitudinal fissionwhere the original anemone splits across the middle, forming two equal-sized anemones, and basal lacerationin which small parts of the animal Describe fragmentation in asexual reproduction the offspring from the base and form a new anemone.
In echinodermsthe process is usually known as fissiparity a term also used infrequently for fission in general. Some species can intentionally reproduce in this manner through autotomy. This method is more during the larval stages. As this process is a form of asexual reproduction, it does not produce genetic diversity in the offspring.
Therefore, these are more vulnerable to changing environments. From Wikipedia, the free encyclopedia. Each of these fragments develop into matured, fully grown individuals that are identical to their parents The splitting may or may not be intentional — it may or may not occur due to man-made or natural damage by the environment or predators. Branch propagation, not cladoptosis, permits dispersive, clonal reproduction of riparian cottonwoods.

The rotes of asexual facsimile fluctuate greatly bulk otherwise types of species. Some protozoans and numerous bacteria, plants and fungi repeat via spores.
Spores are structures innately grown as quota of an organism's vigour run and designed in the interest of splitting from the creature and dispersal via a avenue such as parade or not function. When conditions are the creature command let off its spores, which are each when considered from head to toe disjoined and autonomous organisms.
