Question

Which of the following is not offered as evidence in support of the endosymbiotic theory, the belief that a eukaryotic cell has evolved as a committee of prokaryotic cells?

• A. Mitochondria and chloroplasts are similar in size and structure to some species of bacteria.
• B. The ribosomes of chloroplasts and mitochondria are similar to eubacteria.
• C. Mitochondria and chloroplasts can actively break away from eukaryotic cells and live on their own.
• D. Mitochondria and chloroplasts have their own DNA coding separate from the eukaryotic nucleus.

Answer 1

The correct option is C Mitochondria and chloroplasts can actively break away from eukaryotic cells and live on their own.

C. Mitochondria and chloroplast can activley break away from eukaryotic cells and live on their own.

Reason : The endosymbiotic theory supports that eukaryotic cell organelles have prokaryotic origins like mitochondria, chloroplast etc. This theory have some legit evidences as the presence of extra nuclear genetic material in mitochondria and chloroplast. But it doesn't support the statement as those organelles can break away from the cell because if they do so, the possibility of their survival will be decreased.

So the correct option is C.
