Ribosomes in chloroplasts and mitochondria

How is finding of ribosomes in chloroplasts and mitochondria explained?

Verified

It is strong hypothesis which mitochondria and chloroplasts were prokaryotes that closed to primitive eukaryotic cells under the mutualism (gaining protection and providing energy). This explains why in those organelles there are DNA as well as protein synthesis machinery, comprising ribosomes. This hypothesis is recognized as the endosymbiotic hypothesis on the foundation of chloroplasts and mitochondria.
