Endosymbiosis in Biological Definition

Endosymbiont

... or cells of another organism, i.e. forming an endosymbiosis ( Greek : endo = inner and biosis = living). ... bacterial endosymbionts. Many other examples of endosymbiosis exist. Many instances of endosymbiosis are obligate, where neither the endosymbiont nor ...

Endosymbiotic theory

... driven by competition is incomplete. However, others have argued that endosymbiosis involves helotry rather than mutualism. The possibility that ... Evidence that mitochondria and chloroplasts arose via an ancient endosymbiosis of a bacteria is as follows: Both mitochondria and chloroplasts ...

Symbiosis

... may be divided into two distinct categories: ectosymbiosis and endosymbiosis . In ectosymbiosis, the symbiont lives on the body surface of the host, ... to its host. The biologist Lynn Margulis , famous for the work on endosymbiosis , contends that symbiosis is a major driving force behind evolution . She ...

Eukaryote

... a single origin, not all plastid-containing groups are closely related. Instead, some eukaryotes have obtained them from others through secondary endosymbiosis or ingestion. Endosymbiotic origins have also been proposed for the nucleus and eukaryotic flagella , but this is not generally accepted, both ...

Lynn Margulis

... theory of the origin of mitochondria as separate organisms that long ago entered a symbiotic relationship with eukaryotic cells through endosymbiosis . "She is best known for her theory of symbiogenesis , which challenges a central tenet of neodarwinism . She argues that inherited variation, ...
