Mitochondria are essential for energy production in cells, with a unique structure that aids in ATP creation. They contain their own DNA, suggesting an evolutionary symbiosis with other cells. Mitochondrial DNA is inherited maternally, making it a valuable tool for tracing genetic history. This organelle plays a crucial role in energy production, cell division, and understanding the history of life.
