An endosymbiont or endobiont is an organism that lives within the body or cells of another organism. Typically the two organisms are in a mutualistic relationship...

Plastids, like mitochondria, have their own DNA and are developed from endosymbionts, in this case cyanobacteria. They usually take the form of chloroplasts...

Trichonympha is referred to as an endosymbiont. However, Trichonympha is also a host to bacterial symbionts. Both as an endosymbiont and as a host, Trichonympha...
