The Endosymbiont Theory, proposed by the American biologist Lynn Margulis in the 1960s, suggests that certain organelles within eukaryotic cells, particularly mitochondria and chloroplasts, originated as free-living prokaryotic organisms. According to this theory, these organelles were once independent prokaryotes that formed a symbiotic relationship with a host eukaryotic cell, eventually evolving into a permanent part of the host cell's structure. The theory revolutionized our understanding of the origin of eukaryotic cells and their complexity.

Endosymbiosis, in general, refers to a relationship where one organism lives within the cells or body of another, often benefiting both organisms. In the case of mitochondria and chloroplasts, _________ ___ __________ _______ _______ ___ ______ __________ ___.
