Summary Introduction
Concept introduction: The endosymbiotic theory is the widely accepted theory related to the evolution of the eukaryotes. The theory explains that “The eukaryotes evolved through a process where different types of free-living prokaryotes became incorporated inside larger prokaryotic cells and eventually developed into mitochondria, chloroplasts, and possibly other organelles”.
