|
|
Both prokaryotic and eukaryotic organisms require oxygen in order to use energy.
|
|
|
Mitochondria and chloroplasts contain DNA similar to bacterial DNA.
|
|
|
Bacteria, mitochondria, and chloroplasts all divide by mitosis, while the cells containing them divide by binary fission.
|
|
|
Bacteria and mitochondria contain many features that are similar to each other but different from those of chloroplasts.

Detailed explanation-1: -The endosymbiotic theory proposes that eukaryotic cells arose from living communities formed by the merging of prokaryotic organisms and their hosts. What is evidence to support the endosymbiotic theory?-Mitochondria and chloroplasts contain DNA similar to bacterial DNA.
Detailed explanation-2: -The leading hypothesis, called the endosymbiotic theory, is that eukaryotes arose as a result of a fusion of Archaean cells with bacteria, where an ancient Archaean engulfed (but did not eat) an ancient, aerobic bacterial cell.
Detailed explanation-3: -The theory of how mitochondria, chloroplasts and other membrane-bound organelles in eukaryotic cell likely arose from a symbiosis between aerobic prokaryotes and host anaerobic eukaryotic ancestors. Developed by Lynn Margulis.
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.
