Which cell organelle is known as the 'powerhouse of the cell' due to its role in cellular respiration and ATP production?

💡 Solution & Explanation

Mitochondria are designated as the powerhouses of the cell because they execute aerobic cellular respiration to generate adenosine triphosphate, which fuels metabolic functions. Other options like ribosomes are responsible for protein synthesis, whereas lysosomes handle intracellular digestion and waste disposal. Mitochondria possess their own independent circular DNA distinct from nuclear DNA.
