Mitochondria are small, rod-shaped organelles found in the cytoplasm of eukaryotic cells. They are known as the "powerhouses of the cell" because they produce the majority of the cell's energy in the form of ATP (adenosine triphosphate) through a process called cellular respiration.


In addition to their role in energy production, mitochondria have several other important functions in the cell. For example, they are involved in the synthesis of lipids and certain amino acids, and they play a role in the regulation of cell death (apoptosis).


Mitochondria are surrounded by a double membrane, with the inner membrane being highly folded into cristae. The space between the two membranes is called the intermembrane space, while the space inside the inner membrane is called the matrix. The inner membrane is the site of the electron transport chain, which is responsible for producing most of the ATP.


Mitochondria contain their own DNA and ribosomes, which are used to synthesise proteins needed for their own function. This DNA is separate from the DNA found in the nucleus of the cell, and is thought to be the remnants of ancient bacteria that were engulfed by a larger cell in a process called endosymbiosis.


Overall, mitochondria are vital organelles that play a crucial role in the energy production and overall function of the cell.
