Introduction into Symbiosis
Symbiosis refers to the close association between two or more different biological species, the interaction between these different organisms can either be damaging or valuable to the host symbiont. This association between the symbionts allows these species to undergo organismal evolution and variation in an assortment of ways (Takahiro, Yoshiko, Naruo, Manabu, Nori, Takema 2016). Symbiosis comes in three main forms of interaction; mutualistic, communalistic and parasitic (Hirsch, 2004). The theory behind the origins of eukaryote organelles proposes that they arose from free-living organisms that established a symbiotic association with the host cells (Schwartz & Dayhoff, 1978). The endosymbiont theory refers to the collection of principles that models the origins of the mitochondrion, which commenced with the engulfing of a bacterium by an archaeon (Godfrey-Smith, 2015). Such an establishment at cellular and organism levels is of high importance for environmental, agricultural and organismal health (Wilson & Douglas, 2010). It is widely acknowledged that mitochondria have arisen from an endosymbiotic partnership between bacteria and a host eukaryotic cell and hence this model will be used to explain the origins of the mitochondria and chloroplast. The origins of Eukaryotic cells and its evolution, as well as the novel capabilities as a result of symbiosis is increasingly being recognised as an applied importance and hence will be the key focus…
