11. Explain the endosymbiotic theory and how it relates to the

complexity of the cell.

According to the Endosymbiotic theory, eukaryotic cells came to exist because prokaryotic cells surrounded and incorporated bacteria. These bacteria eventually became organelles. The scientific explanation of cell complexity concerning Endosymbiotic theory is also likely to reveal that organelles in eukaryotic cells are genetically similar to species of Archaea.
