Fragmentation (reproduction)
Fragmentation in multicellular or colonial organisms is a form of asexual reproduction or cloning, where an organism splits into fragments upon maturation, creating a new individual if the split part is large enough.
The organism may develop specific organs or zones to shed or be easily broken off. If the splitting occurs without the prior preparation of the organism, both fragments must be able to regenerate the complete organism for it to function as reproduction.
Fragmentation as a method of reproduction is seen in organisms such as spirogyra, filamentous cyanobacteria, molds, lichens, sponges, acoel flatworms, some annelid worms and sea stars.
Molds, yeasts 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.
Many lichens produce specialized structures that can easily break away and disperse. These structures contain both 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 trees, shrubs, nonwoody perennials, and ferns form clonal colonies by producing new rooted shoots by rhizomes or stolons, which 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 division, layering, cuttings, grafting, micropropagation and storage organs, such as bulbs, corms, tubers and rhizomes.
Many algae too, spirogyra for example also fragment, the mother plant breaks into two or more smaller fragments which then grow independently. After growing these individual spirogyra fragment, repeating the cycle.
