QUESTION 8
Which of the following observations constitutes evidence that mitochondria evolved before chloroplasts?
O Mitochondria are aerobic. Chloroplasts are photosynthetic.
O Aerobic bacteria evolved before photosynthetic bacteria (cyanobacteria).
O Some protists have separately evolved their own plastids (chloroplast-like structures) through endosymbiosis of cyanobacteria, or even through endosymbiosis of
photosynthetic protists.
O All Eukaryotes have mitochondria; only a subset of Eukaryotes have chloroplasts.
