According to one hypothesis, once there was the ancestor of a eukaryotic cell, which swallowed a bacterium. But instead of digesting it, the eukaryotic cell used the bacterium to yield energy by feeding it. In other words, a symbiosis formed, where the former bacterium is protected from foes and gets sugar, whereas the eukaryote gets ATP.
This hypothesis is based on the facts of
- the double cell wall of the mitochondria (the inner one rough like a bacterium one, the outer smooth like from a lysosome)
- the own DNA of the mitochondria
- the 70S ribosomes (like bacteria have it) instead of eukaryotic 80S ribosomes

6. What is believed to be the evolutionary origin of mitochondria?
A bacteria that moved into a cell and stayed alive.
What parts of a cell do scientists think were once free-living organisms?
Mitochondria and chloroplasts are thought to have once been a free prokaryotic cell.
Do mitochondria and choloroplast independently?
Mitochondria and chloroplasts are thought to have evolved independently. While they share some similarities, such as their own DNA and ability to generate energy in the form of ATP, their origin and function differ. Mitochondria likely originated from ancient bacteria that were engulfed by primitive eukaryotic cells, while chloroplasts are believed to have evolved from photosynthetic cyanobacteria that were also engulfed by eukaryotic cells.
Why did the mitochondria originate?
Mitochondria likely originated from a symbiotic relationship between early eukaryotic cells and aerobic bacteria. This symbiosis allowed for more efficient energy production through aerobic respiration, providing a survival advantage which led to the integration of the bacteria as mitochondria within eukaryotic cells.
Can replacing mitochondria DNA with a mitochondria DNA from plant of higher yield improve the yield of crop?
I do not think so as mitochondria are ancestral to all eukaryotes and produce about 36 ATP per glucose molecule on average. I can not think that the higher yield plant would have more efficient mitochondria as plant yield is tied in with plant reproduction and more resources are given over to this process, not more energy. I could be wrong about this though and if I find anything I will post an amended answer.
What is the origin of mitochondria and chloroplast?
They are origined from bacteria.They were evolved through endosymbiotic living.

Which cellular organelle uses oxygen and glucose to provide energy?
The mitochondria is the organelle that uses oxygen and glucose to produce energy in the form of ATP through a process called cellular respiration.
What do some researchers think about hypnosis?
role playing
What are two cell types that have the most mitochondria How many mitochondria do each of the cell types have Why do you think this is so?
Skeletal Muscles. 300 mitochondria. Activities that you do. Cardiac Muscles. 200 mitochondria. Heart pumps so it needs energy.
What is the origin of the surname 'Martines'?
I think the origin is Martins, that's portuguese, it pronunces "Martens", I think..
What is the endosymbiotic theory?
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.
