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)

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:

  • Mitochondria and chloroplasts have some genetic information of their own, which would support their original independence.
  • Both the mitochondria and the chloroplast have their own circular double-stranded DNA freely inside them, independent of the nuclear one.
  • They behave like a bacterium, because they synthesize their own proteins, use 70s ribosomes (and not 80s ribosomes like eukaryotes), perform their functions through the membrane and replicate their DNA and perform binary fission to divide.

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