Detailed explanation-1: -The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear.

Detailed explanation-2: -In endosymbiotic theory, it posited that the larger cell engulfed or took in the smaller cell. The larger cell represents the eukaryotic cell of today whereas the smaller cell is the prokaryotic cell.

Detailed explanation-3: -The endosymbiotic theory posits that some eukaryotic cell organelles, such as mitochondria and plastids, evolved from free-living prokaryotes. Available data indicate that the mitochondrial endosymbiosis initiated the evolution of the eukaryotic cell, as suggested by Margulis.

Detailed explanation-4: -The endosymbiotic theory proposes that eukaryotic cells arose from living communities formed by the merging of prokaryotic organisms and their hosts.

Detailed explanation-5: -The endosymbiotic theory is the accepted mechanism for how eukaryotic cells evolved from prokaryotic cells. It involves a cooperative relationship between two cells which allow both to survive-and eventually led to the development of all life on Earth.
