A representation of the endosymbiotic theory. An endosymbiont or endobiont [1] is an organism that lives within the body or cells of another organism. Typically the two organisms are in a mutualistic relationship.
Symbiogenesis (endosymbiotic theory, or serial endosymbiotic theory [2]) is the leading evolutionary theory of the origin of eukaryotic cells from prokaryotic organisms. [3]
Ectosymbiosis is defined as a symbiotic relationship in which one organism lives on the outside surface of a different organism. [3] For instance, barnacles on whales is an example of an ectosymbiotic relationship where the whale provides the barnacle with a home, a ride, and access to food.
Fungal-bacterial endosymbiosis encompasses the mutualistic relationship between a fungus and intracellular bacteria species residing within the fungus. Many examples of endosymbiotic relationships between bacteria and plants, algae and insects exist and have been well characterized, however fungal-bacteria endosymbiosis has been less well described.
The protist Mixotricha paradoxa, itself an endosymbiont of the Mastotermes darwiniensis termite, is always found as a consortium of at least one endosymbiotic coccus, multiple ectosymbiotic species of flagellate or ciliate bacteria, and at least one species of helical Treponema bacteria that forms the basis of Mixotricha protists' locomotion.

She came home too!" shared one mom. "I literally screamed when I saw this! How lucky are those sweet souls have been to be found and rescued by you. We need more people like you," one commenter added.
Symbiodinium is a genus of dinoflagellates that encompasses the largest and most prevalent group of endosymbiotic dinoflagellates known and have photosymbiotic relationships with many species. These unicellular microalgae commonly reside in the endoderm of tropical cnidarians such as corals , sea anemones , and jellyfish , where the products of ...
An elaborate parody appears to be behind an effort to resurrect Enron, the Houston-based energy company that exemplified the worst in American corporate fraud and greed after it went bankrupt in 2001.
