When one organism takes up permanent residence within another, such that the two become a single functional organism. Mitochondria and plastids are believed to have resulted from endosymbiosis.
The hypothesis that mitochondria and chloroplasts are the descendants of ancient prokaryotic organisms from the domain Bacteria.
A mutually beneficial relationship between two organisms in which one, the endosymbiont, lives within the tissues or the cells of the other, the host.
(Greek, endon = within + syn = together + bios = life) The close association of two organisms, one of which lives inside the other. The mitochondria within all our cells today are thought to have been derived from just such an arrangement.
Gr. endon: within + syn: together + bios: life] • The living together of two species, with one living inside the body (or even the cells) of the other.
the condition in which organism lives within the cells or body or another
symbiosis with symbiont dwelling within the body of its symbiotic partner
The theory that complex, eukaryotic organisms arose when free-living bacteria became trapped in larger cells and forged a symbiotic relationship. These trapped bacteria are thought to have evolved into chloroplasts and mitochondria, which still have their own DNA. (see also: , )
a relationship in which one organism (the symbiont) lives inside another (the host) and in which both partners benefit.
Symbiosis in which one member (microsymbiote) lives within the other. ( 20)
Theory that attempts to explain the origin of the DNA-containing mitochondria and chloroplasts in early eukaryotes by the engulfing of various types of bacteria that were not digested but became permanent additions to the ancestral "eukaryote".
Symbiosis in which one organism lives within the body of the other. More specifically refers to the theory that eukaryotic cells arose from the symbiosis of a number of organisms, with the organelles such as mitochondria and chloroplasts being descended from bacteria.
