The theory of endosymbiosis describes the probable evolution of what type of cell?

Answer 1

Endosymbiosis possibly resulted in the evolution of eukaryotic cells.

Proteobacteria and mitochondria are very similar. The only way mitochondria can reproduce is by binary fission, which is the most common way that bacteria and archaea reproduce.

Another characteristic that both mitochondria and chloroplasts have in common with bacteria is their circular DNA.

It is possible that mitochondria and chloroplasts were free-living organisms similar to cyanobacteria and proteobacteria from the Rickettsiales family, respectively.

They grew symbiotic with other free-living cells and eventually lost their capacity for independence.

Genetic material from mitochondria and chloroplasts is transferred to the nucleus.
