GENERAL HISTOLOGY

Detailed explanation-1: -7.2 Primary and Secondary Endosymbiosis. A symbiotic relationship where one organism lives inside the other is known as endosymbiosis. Primary endosymbiosis refers to the original internalization of prokaryotes by an ancestral eukaryotic cell, resulting in the formation of the mitochondria and chloroplasts.

Detailed explanation-2: -We have identified the first human endosymbiont and generated a novel antibody which detects it. The existence of endosymbionts in human tissue is not readily apparent without the antibody, explaining why they have not been seen previously.

Detailed explanation-3: -Endosymbiosis is a form of symbiosis wherein the symbiont lives within the body of its host and the symbiont in an endosymbiosis is called an endosymbiont. An example of an endosymbiosis is the relationship between Rhizobium and the plant legumes. Rhizobium is the endosymbiont that occur within the roots of legumes.
