Endosymbiotic theory provides an explanation of how the first eukaryotic cells may have formed and why DNA can be found in the organelles inside the cells. What does this theory suggests? Eukaryotes were much larger cells that took over the food supply and resources.

Eukaryotes were very similar to the early bacteria just a little larger in size.

Eukaryotes consumed photosynthetic bacteria and made them part of the make up of the cell,

Bacteria fused together to make a larger cell that contained more DNA.
