Question

Quizplus · Accepted Answer

Prokaryotic cells are not at an evolutionary disadvantage because they lack organelles. While eukaryotic cells have specialized organelles such as mitochondria and chloroplasts, prokaryotic cells are still able to carry out necessary processes such as metabolism and reproduction. In fact, prokaryotic cells have been able to thrive and evolve for billions of years without the need for internal membrane-enclosed organelles. So, while eukaryotic cells may have higher efficiency due to their specialized organelles, prokaryotic cells are not at a disadvantage without them.
