Question 11

According the endosymbiont theory we can reason that the merging event that led to the mitochondria occurred before the merging event that led to the chloroplast because all eukaryotic cells which have chloroplasts also have mitochondria, but all cells that have mitochondria do not necessarily have chloroplasts.
