What are 2 characters about mitochondria and chloroplast that make them similar to prokaryotic bacteria cells?

Following are two characteristics of mitochondria and chloroplast that are similar to prokaryotic cells:

Explanation:

Endosymbiotic Theory:

The endosymbiotic theory helps explain the origins of multi-cellular organisms. An endosymbiont is defined as an organism that lives inside another organism in a state of "endosynmbiosis." The theory states that some of cellular organelles were originally separate prokaryotic organisms engulfed by an amoeba like organism. These engulfed prokaryotes sustained inside the amoeba and evolved into present day mitochondria and chloroplasts.

Apart from the aforementioned similarities, mitochondria and chloroplasts are roughly the same size as a prokaryotic cell and can self replicate by binary fission.

i believe it would be the lungs.
