According to the endosymbiotic theory of the origin of eukaryotic cells, how did chloroplasts originate?   -by tertiary endosymbiosis -through secondary endosymbiosis -from the nuclear envelope folding outward and forming mitochondrial membranes -from infoldings of the plasma membrane, coupled with mutations of genes for oxygen-using metabolism -through primary endosymbiosis
