More Information
Mitochondria are often referred to as the powerhouses of the cell due to their role in energy production through ATP. They also contain their own genetic material, allowing them to generate some of their own proteins independently.
Tips
A common mistake is confusing the unique features of mitochondria with those of chloroplasts, which are also double-membraned and contain their own DNA but are distinct in their role in photosynthesis.
