The first eukaryotic organisms were formed by the process known as endosymbiosis whereby once independent microorganisms entered cells of other independent microorganisms and established symbiotic relationships with each other.
Endosymbiosis occurred when one prokaryote engulfed another prokaryote and they began living together in a mutually beneficial relationship. This lead to the development of eukaryotes.
from engulfed, originally free-living prokaryotes
The endosymbiotic event occurred around120 million years ago. But it took thousands of years for the evolution to occur.
Endosymbiotic theory describes how mitochondria and chloroplast evolved.Mitochondria was evolved by aerobic bacteria.Chloroplast evolved by photosynthetic bacteria.
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.
Both contain DNA
The Hypothesis Must Be Supported In Order For It To Become A Theory
A scientific theory presents an explanation for a phenomenon. Using that explanation, one can then make predictions about what will happen under certain conditions. But the prediction is not the theory, it is a implication of the theory.

The Endosymbiotic theory of Lynn Margulis.
This is the endosymbiotic theory.
Lynn Margulis first proposed the theory of endosymbiosis.
Eukaryotes
Endosymbiotic theory describes that.It shows photosynthetic and aerobic bacteria engulfed by eulariyotic cells turned into chloroplst and mitochondria.
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.
Since it is a theory, it can not be determined if it is in fact true. There are some who believe it and some who do not believe it.
Chloroplasts and mitochondria according to the endosymbiotic theory.

Endosymbiotic Theory
Mitochondria and chloroplasts reproduce independently from the cell.
