2. Mitochondria divide separately from the division of the cell itself and do so in a manner similar to binary fission. Mitochondria divide independently of the cell. 3.
The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear. Mitochondria and chloroplasts have their own ribosomes which have 30S and 50S subunits, not 40S and 60S. Endosymbiotic theory proposes that these organelles were once prokaryotic cells, living inside larger host cells.
-evolutionary theory of the origin of eukaryotic cells from prokaryotic the endosymbiont or the host cannot survive without the other.

An endosymbiont is one organism that lives inside of another one. All eukaryotic cells, like your own, are creatures that are made up of the parts of other creatures. Mitochondria, the important energy generators of our cells, evolved from free-living cells.

endosymbiotic theory: Much of the internal structure and biochemistry of chloroplasts, for instance the presence of thylakoids and particular chlorophylls, is very similar to that of cyanobacteria. The size of both organelles is comparable to bacteria. These organelle's ribosomes are like those found in …

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.
