DNA from these organelles show higher sequence similarity to eubacterial DNA than to eukaryotic DNA. B. these organelles both possess double membranes, unlike other organelles. C. these organelles both generate ATP. D. these organelles both possess ribosomes that are similar to eubacterial ribosomes. E. Actually, all of these data support the endosymbiotic theory.

Explanation / Answer

E. Actually, all of these data support the endosymbiotic theory.

The endosymbiotic theory simply suggests that the mitochondria and chloroplast are actually symbiotic bacteria who resided in the cells of primitive eukaryotes. Therefore, all there characteristics are similar /almost similar to prokaryotes.
