Answer:
Eukaryotes have mitochondria and chloroplasts with structures and functions similar to those of prokaryotes.
Explanation:
The endosymbiotic theory was created by an American biologist called Lynn Margulis. The theory proposes that eukaryotic cells are produced from a symbiotic relationship among prokaryotic cells. It describes how eukaryotic cells became so complex and it suggested that membrane bound organelles such as mitochondria and chloroplasts were once free-living prokaryotic cells that later started living within a bigger host cell. After a long time, the organelles and the prokaryotes evolved together and are dependent on each other.
