Describe what endosymbiotic theory is. it is a theory that explains the evolutionary history of prokaryotic cells. early eukaryotes were able to engulf other eukaryotic cells resembling chloroplast and mitochondria forming an endosymbiotic relationship it is a theory that explains the evolutionary history of eukaryotic cells. early prokaryotes were able to engulf other prokaryotic cells resembling chloroplasts and mitochondria forming an endosymbiotic relationship.

first published by lynn margulis in the late 1960s, the endosymbiont theory proposed that the main organelles of the eukaryotic cell were actually primitive prokaryotic cells that had been engulfed by a different, bigger prokaryotic cell. the term "endosymbiosis" means "to cooperate inside". whether the larger cell provided protection for the smaller cells, or the smaller cells provided energy to the larger cell, this arrangement seemed to be mutually beneficial to all of the prokaryotes.
