Answer:

1- They have circular DNA, RNA and 70s ribosomes

2- They reproduce by binary fission

3- They can synthezise ATP

Explanation:

Mitochondria and chloroplasts are semi-autonomous organelles that are similar in many aspects:

  • Both of them have a similar size with bacterias,
  • Both of them have enzymes that synthesize ATP,
  • Both of them have DNA, RNA, and 70s ribosomes, these last ones characteristic of prokaryotes. They are capable of synthesizing proteins. Their DNA is circular and double-stranded,
  • Both of them reproduce by binary fission, as prokaryotes do.

Because of all of these characteristics, mitochondria and chloroplasts are suggested to be once free-living bacterias.
