It is believed that cellular irganelles such as mitochondria and chloroplasts arose within eukaryotic cells by a series of intracellular endosymbioses. Interaction of cytosolic and plastidic nitrogen metabolism in plants. A symbiotic relationship may be parasitic one partner harming the othercommensal usually not affecting each other or beneficial unilaterally or mutually.

Many of both intracellular and extracellular endosymbionts form obligate endosymbioses, in which neither the emdosymbionts nor their hosts can live without the other.
How protein targeting to primary plastids via the endomembrane system could have evolved? Molecular evolutionary analyses of nuclear-encoded small endosymboonts ribosomal RNA identifyan independent rhizopod lineage containing the Euglyphina and theChlorarachniophyta. Estimating the timing of early eukaryotic diversification with multigene molecular clocks. In particular it describes how the interplay of reductive genome evolution, gene transfers, and trafficking of host-encoded proteins into the cyanobacterial endosymbiont contributed to transform the symbiont into a nascent photosynthetic organelle.
