Detailed explanation-1: -Both mitochondria and chloroplasts contain their own DNA and ribosomes.

Detailed explanation-2: -The chloroplast is double membrane-bound organelles which are separated by fluid-filled intermembrane space. Their genetic material consists of DNA, RNA, along with ribosome, and certain enzymes.

Detailed explanation-3: -Chloroplasts and mitochondria are subcellular bioenergetic organelles with their own genomes and genetic systems.

Detailed explanation-4: -Chloroplasts (members of the plastid family) and mitochondria are central to the energy cycles of ecosystems and the biosphere. They both contain DNA, organized into nucleoids, coding for critical genes for photosynthetic and respiratory energy production.

Detailed explanation-5: -Consistent with their postulated origin from endosymbiotic cyanobacteria, chloroplasts of plants and algae have ribosomes whose component RNAs and proteins are strikingly similar to those of eubacteria.
