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 suggests that mitochondria and chloroplasts were once free - living prokaryotes. Prokaryotes are small. If mitochondria and chloroplasts were much larger than prokaryotic cells, it would not support the idea that they were once similar to prokaryotes.

• Mitochondria and chloroplasts reproducing independently supports the idea that they were once independent organisms.
• Having their own ribosomes (similar to prokaryotic ribosomes) supports the theory.
• DNA resembling bacterial DNA also supports the endosymbiotic theory as it implies a prokaryotic origin.

Answer:

Mitocondria and chloroplasts are much larger than prokaryotic cells.
