Endosymbiotic theory describes the evolution of mitochondria and chloroplast.According to it,photosynthetic bacteria and aerobic bacteria engulfed by a eukaryotic cell turned into chloroplast and mitochondria.
two membranes, for example the mitochondrion and the chloroplast.
DNA is stored on chromosomes, and chromosomes are passed through generations.
The mitochondria. They contain a small amount of their own DNA.
This is a relatively complicated question as the exact origins of mitochondria and how they came to be included in eukaryotic cells is still under investigation and therefore open to debate.Everyone seems to agree though, that they originally come from bacterium and that they were assimilated into eukaryotic cells either because they were useful or through some form of symbiosis.As mitochondria are common to both plant and animal cells it could therefore be argued that they shared a common ancestor at some point in evolution.The inclusion of the chloroplast came later, and a separate line of mitochondrial and chloroplast carrying cells evolved - eventually becoming plants. The line without the chloroplast becoming animals.
The concept that explains the presence of mitochondria in cells is the endosymbiotic theory. Mitochondria in cells derived from the extra embryonic membranes.

the likely orign of mitochondria is like this random glup of toop. It has all that Shmuff in it.
The Endosymbiotic Theory is a theory about how mitochondria and chloroplasts formed. The theory suggests that both the mitochondria and chloroplasts were once prokaryotic cells that were ingested but not digested by eukaryotic cells. This would explain why both have their own DNA.

Nucleus Mitochondria
There is a theory that chloroplast and mitochondria were independent organisms. Since they were, they would have their own DNA. And it is true that they do. It is interesting that you get your mitochondria from only your mother. There are many studies have used mtDNA to trace the evolution and migration of human species, including when the common ancestor to modern humans and Neanderthals lived.

it is a Theory! :)
because in the past it was an independent bacteria, which swallowed later by eukaryotic cell - according the the Endosymbiotic Theory.
