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

Mitochondria

The correct answer is Option (2)- Mitochondria

The organelle of the cell that is also known as the "powerhouse of the cell" is the Mitochondria.

Mitochondria:

• Mitochondria are double-membraned organelles found in the cytoplasm of eukaryotic cells.
• They are often referred to as the powerhouse of the cell because they play a central role in cellular respiration.
• Cellular respiration is the process by which cells generate energy (in the form of ATP - adenosine triphosphate) from the breakdown of glucose in the presence of oxygen.
• Mitochondria contain their own DNA and are believed to have originated from an ancient symbiotic relationship between eukaryotic cells and bacteria.

The production of ATP in mitochondria is essential for various cellular activities and is a key aspect of energy metabolism in eukaryotic cells.
