Question

endosymbiotic theory
which statement is evidence used to support the endosymbiotic theory?
mitochondria and chloroplasts contain their own dna.
mitochondria and chloroplasts are surrounded by one membrane.
mitochondria and chloroplasts reproduce similar to eukaryotic cells: through mitosis.

Explanation:

The endosymbiotic theory posits that mitochondria and chloroplasts were once independent prokaryotic organisms that were engulfed by a larger cell. Evidence includes them having their own DNA, similar to prokaryotes. Mitochondria and chloroplasts are surrounded by a double - membrane, not a single one. They reproduce by binary fission like prokaryotes, not mitosis like eukaryotic cells.

Answer:

Mitochondria and chloroplasts contain their own DNA.
