One piece of supporting evidence for the endosymbiotic theory for the origin of eukaryotic cells is that: a. Eukaryotic cells have internal membranes. b. Mitochondria and chloroplasts have their own DNA. c. Golgi bodies and endoplasmic reticulum were present in ancestral cells. d. The nuclear membrane could only have come from another cell.

Step 1
Eukaryotic cells having internal membranes is not specific evidence for endosymbiotic theory, as it could be a result of other evolutionary processes. b. Mitochondria and chloroplasts having their own DNA supports the idea that they were once independent Show more…
