12 stairway2evan It's actually believed that chloroplasts and mitochondria used to be their own unique, single-celled organisms, which evolved to work symbiotically with the bigger, eukaryotic (more complex, with a true nucleus) cells that were beginning to develop and become more complex. The relationship made a lot of sense: the chloroplasts and mitochondria would get lots of free food from the host organism, and in exchange it would help make energy for its host through photosynthesis or respiration processes. So those two organelles kept their DNA through today, because they're still kind of their own thing. That also leads to an interesting quirk: because a female's egg cells contain mitochondria but a male's sperm cells don't, all mitochondrial DNA is passed down from the mother - in other words, I have my mom's mitochondria, but not my dad's. This can be used to track descent down the female line.
4 PrionBacon There's a theory that eukaryotic cells started out as large cells that managed to form symbiotic relationships with other smaller cells. The smaller cells eventually turned into organelles like the chloroplasts. The organelles essentially live and reproduce within the larger eukaryotic cells while providing a great deal of benefits like generating energy from light (chloroplasts) and enhanced aerobic energy generation (mitochondria). This is why larger life forms are generally formed from eukaryotic cells. Mitochondria also contain DNA. Mitochondria is only provided by the female egg (the sperm only contributes nuclear DNA) so mitochondrial DNA can be used to track genetic changes passed down by females.
4 cdbloosh Nobody knows for sure but one theory is that chloroplasts and mitochondria were originally independent prokaryotic cells that eventually were incorporated into other cells in some sort of symbiotic/cooperative relationship.
