What is the endosymbiotic hypothesis of the origin of the eukaryotic cell?
Wiki User
∙ 12y ago
The theory is that the original Eukaryotic cell came about by the consumption of a Prokaryotic cell by another Prokayotic cell. This smaller cell was incorporated into the processes of the other - thus forming a symbiosis.
This theory is supported by the fact that chloroplasts and mitochondria have their own DNA (separate from the nucleus).

What is the autogenic hypothesis of the origin of the eukaryotic cell?
Autogenic means produced from within, or self-generating. Therefore the 'autogenic hypothesis' is most likely to be that the organelles and structures of a Eukaryotic cell were self-generated by a Prokaryotic cell - and this is how Eukaryotic cells were created. The theory of Endosymbiosis is much more widely accepted.
What is a membrane bound organelle plant cells?
Mitochondria and Chloroplasts, this is to do with the endosymbiotic theory.
Which eukaryotic kingdom includes members that are the result of endosymbioses that included an ancient proteobacterium and an ancient cyanobacterium?
In 1905, the Russian biologist C. Mereschkowsky postulated that plastids (e.g., chloroplasts) are the evolutionary descendants of endosymbiotic cyanobacteria-like organisms. In 1927, I. Wallin explicitly postulated that mitochondria likewise evolved from once free-living bacteria. Here, we summarize the history of these endosymbiotic concepts to their modern-day derivative, the "serial endosymbiosis theory", which collectively expound on the origin of eukaryotic cell organelles (plastids, mitochondria) and subsequent endosymbiotic events. ...So either the answer is Plantae or maybe animalia? my bet is Plantae. *edit - Its Plantae :)
Is a fat cell a prokaryotic or a eukaryotic cell?
A fat cell is a eukaryotic cell. All of the cells in a eukaryotic organism are eukaryotic.
Why are mitochondria able to make their own protein?
because in the past it was an independent bacteria, which swallowed later by eukaryotic cell - according the the Endosymbiotic Theory.

What is the origin of chloroplasts?
Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion. Eukaryotic cells containing mitochondria then engulfed photosynthetic prokaryotes, which evolved to become specialized chloroplast organelles.
How mitochondria or chloroplasts evolved?
Endosymbiotic theory describes the evolution of mitochondria and chloroplast.According to it,photosynthetic bacteria and aerobic bacteria engulfed by a eukaryotic cell turned into chloroplast and mitochondria.

What model is used to explain the origin of mitochondria and chloroplasts within eukaryotic cells?
I believe you are referring to the Endosymbiotic theoryby Lynn Margulis. She came up with the theory that states that eukaryotic cells engulfed smaller bacteria and over time, they became specialized organelles within eukaryotic cells.
What do researchers think the origin of mitochondria are and why?
According to one hypothesis, once there was the ancestor of a eukaryotic cell, which swallowed a bacterium. But instead of digesting it, the eukaryotic cell used the bacterium to yield energy by feeding it. In other words, a symbiosis formed, where the former bacterium is protected from foes and gets sugar, whereas the eukaryote gets ATP.This hypothesis is based on the facts ofthe double cell wall of the mitochondria (the inner one rough like a bacterium one, the outer smooth like from a lysosome)the own DNA of the mitochondriathe 70S ribosomes (like bacteria have it) instead of eukaryotic 80S ribosomes
Is a mitochondria a bacterial Cell?
Yes, according to the The endosymbiotic theory:The endosymbiotic theory concerns the mitochondria, plastids (e.g. chloroplasts), and possibly other organelles of eukaryotic Cells. According to this theory, certain organelles originated as free-living bacteria that were taken inside another Cell as endosymbionts. Mitochondria developed from proteobacteria (in particular, Rickettsiales or close relatives) and chloroplasts from cyanobacteria.
