Question

which statement does not support the endosymbiotic theory?
mitochondria and chloroplasts reproduce independently from the cell.
mitochondria and chloroplasts contain their own ribosomes.
mitochondria and chloroplasts have dna that resembles bacterial dna.
mitochondria and chloroplasts are much larger than prokaryotic cells.

Explanation:

The endosymbiotic theory posits that mitochondria and chloroplasts were once free - living prokaryotes that were engulfed by a larger cell. Evidence for the theory includes independent reproduction, presence of their own ribosomes, and DNA similar to bacterial DNA. However, if mitochondria and chloroplasts were much larger than prokaryotic cells, it would go against the idea that they were once prokaryotes.

Answer:

Mitochondria and chloroplasts are much larger than prokaryotic cells.
