Question

which part of the current eukaryotic cell do scientists think may have been their own independent structure millions of years ago?

Answer 1

Scientists suggest that mitochondria and plastids (e.g. chloroplasts), represent formerly free-living bacteria that were taken inside another cell as an endosymbiont, around 1.5 billion years ago. This is called as \(\bf endosymbiotic~theory.\)
