The two organelles that contain their own DNA and are thought to have originated from free-living organisms are mitochondria and chloroplasts. Both of these organelles have their own circular DNA, similar to bacterial DNA, and they replicate independently of the cell's nuclear DNA. This endosymbiotic theory suggests that they were once separate prokaryotic organisms that entered into a symbiotic relationship with ancestral eukaryotic cells.

Which organelles oils you expect to find only in autotrophic organisms?

In autotrophic organisms, you would expect to find chloroplasts, which are the organelles responsible for photosynthesis. These organelles contain chlorophyll, allowing the organism to convert light energy into chemical energy. Additionally, autotrophs may have other specialized structures related to photosynthesis, but chloroplasts are the key organelles exclusive to this group.
