concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells. According to this theory, these organelles originated as separate prokaryotic organisms which were taken inside the cell as endosymbionts. Mitochondria developed from proteobacteria (in particular, Rickettsiales or close relatives) and chloroplasts from cyanobacteria. concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells.

This is the endosymbiotic theory.

Endosymbiotic theory describes that.It shows photosynthetic and aerobic bacteria engulfed by eulariyotic cells turned into chloroplst and mitochondria.
The Endosymbiotic Theory is a theory about how mitochondria and chloroplasts formed. The theory suggests that both the mitochondria and chloroplasts were once prokaryotic cells that were ingested but not digested by eukaryotic cells. This would explain why both have their own DNA.
Since it is a theory, it can not be determined if it is in fact true. There are some who believe it and some who do not believe it.
Chloroplasts and mitochondria according to the endosymbiotic theory.

By a process called endosymbiosis. The engulfing, for whatever purpose, of the microorganisms that were these now organelles. Google endosymbiotic theory. Lynn Margulis.
