2014-12-01 · Endosymbiotic theory posits that plastids and mitochondria were once free-living prokaryotes and became organelles of eukaryotic cells. The theory started with plastids and was further developed for mitochondria . It was rejected by cell biologists in the 1920s and revived in the 1960s . The endosymbiotic event that generated mitochondria must have happened early in the history of eukaryotes, because all eukaryotes have them. Then, later, a similar event brought chloroplasts into some eukaryotic cells, creating the lineage that led to plants. Which of the following are evidence for the endosymbiotic theory.

Symbiogenesis of mitochondria and plastids.

The idea that chloroplasts were originally independent organisms that merged into a symbiotic relationship with other one An endosymbiont is a cell which lives inside another cell with mutual benefit Eukaryotic cells are believed to have evolved from early prokaryotes that were engulfed by phagocytosis The engulfed prokaryotic cell remained undigested as it contributed new functionality to the engulfing cell (e.g. photosynthesis) The theory postulates that the mitochondria evolved from aerobic bacteria (probably proteobacteria, related to the rickettsias), and that the chloroplast evolved from endosymbiotic cyanobacteria (autotrophic prokaryotes). The evidence for this theory is compelling as a whole, and it is now generally accepted. The theory of how mitochondria, chloroplasts and other membrane-bound organelles in eukaryotic cell likely arose from a symbiosis between aerobic prokaryotes and host anaerobic eukaryotic ancestors.

Because it posits that eukaryotes evolved from the mitochondrial endosymbiosis in a prokaryotic host, this theory directly accounts for the ubiquity of The endosymbiotic theory concerns the origins of mitochondria and chloroplasts, which are organelles of eukaryotic cells. According to this theory, these originated Apr 14, 2021 The endosymbiotic theory holds that organelles within the cells of eukorytes such as mitochondria and chloroplasts, had descended from Jan 10, 2012 Endosymbiotic theory essentially maintains that mitochondria arose by virtue of a symbiotic union of prokaryote cells.

A theory stating that the eukaryotes evolved through a process whereby different types of free-living prokaryotes became endosymbiotic theory n. A theory stating that the eukaryotes evolved through a process whereby different types of free-living prokaryotes became incorporated inside larger prokaryotic cells and eventually developed into mitochondria, chloroplasts, and possibly other organelles.
