Which of the following is true of secondary endosymbiosis?

Which of the following is evidence to support the endosymbiotic theory?

Biologists think that endosymbiosis gave rise to mitochondria before plastids partly because:

Chloroplasts and mitochondria are thought to be of prokaryotic origin. One piece of evidence that supports this hypothesis is that these organelles contain prokaryotic-like ribosomes. These ribosomes are probably most similar to ribosomes found __________.
