What is the difference between primary and secondary endosymbiosis in terms of mitochondrial and plastid evolution?

Primary endosymbiosis involves the uptake of a free-living bacterium by a heterotrophic eukaryote, while secondary endosymbiosis involves the engulfment of a photosynthetic eukaryote by another eukaryote. Signup and view all the answers

Which statement accurately describes the relationship between algae and the evolution of mitochondria and plastids?
