Which organelle is known as the "powerhouse" of the cell?

• Nucleus

• Mitochondria

• Golgi apparatus

• Lysosome

Answer explanation

The correct organelle known as the 'powerhouse' of the cell is the mitochondria. It is responsible for producing energy in the form of ATP through cellular respiration.
