Correct answer and explanation

Correct answer: Mitochondria

Explanation: The Mitochondria is called the 'powerhouse of the cell' because it produces energy in the form of ATP (Adenosine Triphosphate). 📚 Other Information: ▪️ Mitochondria are double-membraned organelles found in all eukaryotic cells. ▪️ They generate ATP through cellular respiration. ▪️ Discovered by Albert von Kolliker (1857) and named by Carl Benda (1898). ▪️ ATP is produced mainly during the Krebs cycle and electron transport chain. ▪️ Mitochondria have their own DNA and ribosomes, showing semi-autonomy. ▪️ Known as the 'cell within a cell' due to independent genetic material. ▪️ Dysfunction in mitochondria leads to muscular and metabolic diseases. ▪️ The number of mitochondria is highest in energy-demanding cells like muscles.
