Which of the following supports the theory of endosymbiosis? a. mitochondria and chloroplasts contain their own set of dna b. prokaryotes are bigger than eukaryotes c, mitochondria and chloroplasts do not contain their own set of dna d. prokaryotes and eukaryotes are often found living away from each other

a. Mitochondria and chloroplasts contain their own set of DNA.

Explanation:

The theory of endosymbiosis suggests that origin of mitochondria and chloroplast in eukaryotes were the individual primitive prokaryotic organisms. The mitochondrial and chloroplast DNA and protein synthesis was found similar to the bacteria. This provided the evidence for endosymbiotic hypothesis. It was determined that chloroplast as well as mitochondria divide independently in the cell where they live just like individual bacterial cell.
