Mitochondria for animal cells and chloroplasts for plant cells.
Early on. when prokaryotes underwent membrane unfolding, got larger and evolved into eukaryotes, early eukaryotes that "ate" up prokaryotes developed a mutually beneficial (symbiotic) relationship with the prokaryote.
Photosynthetic bacteria eventually became chloroplasts in plant cells, and bacteria capable of oxidative phosphorylation (which is seen in the electron transport chain in modern mitochondria) became the mitochondria.
