endosymbiotic hypothesis

endosymbiotic hypothesis The hypothesis that the plastid and mitochondrial organelles evolved from prokaryotic endosymbionts within eukaryotic cells early in eukaryotic evolution. At least two endosymbiotic events are postulated, one each for plastid and mitochondrial origins. It is contentious whether two independent events could account for the mitochondria that occur in plants and those that occur in animals, the present-day mitochondria of the two kingdoms being quite distinct from each other genetically.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
