Chalk Talk Mitochondria

Mitochondria are essential organelles in complex cells, providing energy for cellular functions. Their unique structure, with folds called cristae, aids in ATP production. Mitochondria have their own DNA, suggesting an evolutionary origin as symbiotic bacteria. This DNA is maternally inherited, changing little over time, making it useful for tracing genetic history. Mitochondria play a crucial role in energy production, cell division, and understanding life's history.
