Which statement does not support the endosymbiotic theory? 1.) Mitochondria and Chloroplasts reproduce independently from the cell.
2.) Mitochondria and Chloroplasts contain their own ribosomes.
3.) Mitochondria and Chloroplasts have DNA that resembles bacterial DNA.
4.) Mitochondria and Chloroplasts are much larger than prokaryotic cells.

The statement that does not support the endosymbiotic theory is:

4.) Mitochondria and Chloroplasts are much larger than prokaryotic cells.

Lynn Margulis, in her endosymbiotic theory, proposes that eukaryotic cells evolved by incorporating prokaryotic organisms into their cytoplasm.

This theory is reinforced by the following facts:

Therefore, we can conclude that Mitochondria and Chloroplasts are much larger than prokaryotic cells is the statement that does not support the endosymbiotic theory.

4.) Mitochondria and Chloroplasts are much larger than prokaryotic cells.

no, they are about the same size, another good argument for the endosymbiotic theory is the presence of prokaryotic ribosomes (30S)

instead of copying and pasting things off of tests or work done on computer which im sure you did, try and read over the question carefully
