Detailed explanation-1: -The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes.
Detailed explanation-2: -Explanation: The Endosymbiotic Theory states that the mitochondria and chloroplast in eukaryotic cells were once aerobic bacteria (prokaryote) that were ingested by a large anaerobic bacteria (prokaryote).
Detailed explanation-3: -Summary. Eukaryotic cells probably evolved about 2 billion years ago. Their evolution is explained by endosymbiotic theory. Mitochondria and chloroplasts evolved from prokaryotic organisms.
Detailed explanation-4: -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.
