concept that mitochondria and chloroplasts are the result of years of evolution initiated by the endocytosis of bacteria and blue-green algae which, instead of becoming digested, became symbiotic.
Mitochondria were evolved from bacteria.This is explained by endosymbiotic theory.
endosymbiosis
Take the mitochondria as example. This organelle contains it's own circular DNA that is representative of cyanobacterial DNA. This DNA codes for some proteins also. Some mitochondrial DNA has been taken into the nuclear DNA where it's presence is rather obvious. And the mitochondria fission in reproducing themselves.
Mitochondria and chloroplasts for two contributions here through endosymbiosis.
Eukaryotes evolved from a process call endosymbiosis. Endosymbiosis states that eukaryotes started as two separate bacterium. The bigger bacteria engulfed the smaller. This is how the mitochondria is enclosed in the cell. There is evidence of this because the mitochondria has its on cell membrane and contains its own DNA.

By a process called endosymbiosis. The engulfing, for whatever purpose, of the microorganisms that were these now organelles. Google endosymbiotic theory. Lynn Margulis.

Almost all eukaryotes have mitochondria but only some cells have chloroplasts

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.
Endosymbiosis enabled the formation of true living cells. This concept explains the origin of two biological structures, the mitochondria and the chloroplasts.
Mitochondira are derived from mother cells. They conduct the ETC to produce energy or ATP. It is suggested by endosymbiosis theory that the early precursor engulfed mitochondria which was actually an energy producing bacteria. Mitochondria has its own DNA called as mtDNA.
