Which of the following statements about the endosymbiotic theory is false?

Which of the following statements about the endosymbiotic theory is false?

The entire genome of the ancestral bacteria has been preserved in present-day mitochondria and chloroplasts.

The ancestral bacteria, from which mitochondria and chloroplasts are derived, were capable of photosynthesis and aerobic respiration.

Mitochondria and chloroplasts arose independently from free-living bacteria.

Eukaryotic cells engulfed the ancestral bacteria from which mitochondria and chloroplasts are derived, and the two entities formed a symbiotic relationship.

Answer 1

Answer:- The correct answer is" The entire genome of the ancestral bacteria has been preserved in present day mitochondria and chloroplast.

Because the entire genome of the ancestral bacteria has been not preserved in present day mitochondria and chloroplast.

Endosymbiotic theory state that mitochondria and chloroplast originated from the prokaryotic cells.

According to endosymbiotic theory , the mitochondria and chloroplast may be considered as intra- cellular parasites of the cells which have entered in the cytoplasm of eukaryotic cells in early evolutionary days , and have maintained the symbiotic relations with the eukaryotic cells.

The mitochondria are supposed to be originated from the bacterial cells( purple bacteria) while chloroplast are supposed to be originated from the blue green algae.
