The endosymbiosis theory explains the origins of organelles such as mitochondria and chloroplasts in eukaryotic cells. The theory proposes that chloroplasts and mitochondria evolved from certain types of bacteria that eukaryotic cells engulfed through endophagocytosis.Redirected from Endosymbiotic). A representation of the endosymbiotic theory. An endosymbiont is any organism that lives within the body or cells of another organism, i.e. forming an endosymbiosis (Greek: á¼Î½Î´Î¿Î½ endon within, ÏÏÎ½ syn together and Î²Î¯ÏÏÎ¹Ï biosis living).
Because they evolved without them. Bacteria are a type of prokaryote. All prokaryotes lack membrane bound organelles. This is due to its evolutionary history. It is generally accepted that eukaryotes evolved after prokaryotes, thus membrane bound organelles were not the norm. The most commonly proposed idea, the endosymbiotic theory, suggests that eukaryotes were formed by endocytosis. That is, larger cells would consume smaller cells.
