Other uses Fragmentation disambiguation Fragmentation or Clonal Fragmentation is a form of asexual reproduction or cloning 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 mold s, some annelid worms, and sea star s. Binary fission of single celled organisms such bacteria , protozoa and many algae is a type of fragmentation. Molds, yeast , and mushroom s, all of which are part of the Fungi kingdom biology kingdom , produce tiny filaments called hypha e. 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 a type of Dissociation chemistry chemical dissociation . Fragmentation of a molecule can take place by a process of heterolysis or homolysis . It is a phenomenon observed in mass spectrometry where it is used as a tool to find the structural formula of a molecule, process called structural elucidation . It can occur in the ion source in source fragmentation where it is generally not a desired effect. Ion source conformation is an important criterium in the level of fragmentation observed. Desired fragmentation is made in the collision zone post source fragmentation of a tandem mass spectrometry tandem mass spectrometer . It is a part of gas phase ion chemistry and there are different types of mass fragmentation collision induced dissociation CID , electron capture dissociation ECD , electron transfer dissociation ETD electron detachment dissociation EDD , photodissociation , particularly infrared multiphoton dissociation IRMPD and blackbody infrared radiative dissociation BIRD , surface induced dissociation SID , charge remote fragmentation , Higher energy C trap dissociation HCD .

Unreferenced date August 2008 In economics , fragmentation means organization of Production, costs, and pricing production in which different stages of production are divided among different suppliers that are located in different countries. Now products traded between firms in different countries are components instead of final products. Final products may be sold to outside the region in which fragmentation happens East Asia n countries often sell their final products to European Union Europe and the United States of America USA for example . Producers in less developed countries get positions of production chain that add less value to final product. Their challenge is to climb upwards on transnational production chain. Production chains are often vertical hierarchies in which big multinational companies may be those who sell final products and set production standards for lesser producers.
