Answer:
The evolution of the Eukaryote cell is most likely involves the endosymbiosis of an smaller bacteria that might be aerobic bacteria by a larger bacteria.
Then this smaller bacteria must remain in symbiotic association with the larger bacteria and it must evolve in organelles like chloroplast or mitochondria and the larger prokaryotic cell must be evolved in an Eukaryota cell.
This theory is called endosymbiotic theory and is supported by the similarities of organelle like chloroplast and mitochondria present in eukaryotic cells with prokaryotic cells.
