Question

The endosymbiotic theory suggests that the nucleus was originally a separate prokaryotic organism. t or f

Answer 1

False. The endosymbiotic theory suggests that certain organelles within eukaryotic cells, specifically mitochondria and chloroplasts, originated from free-living prokaryotic organisms that were engulfed by an ancestral eukaryotic cell. The theory does not posit that the nucleus itself was a separate prokaryotic organism.
