Answer:
The powerhouse of the cell
Step-by-step explanation:
The mitochondria is often referred to as the "powerhouse" of the cell because it is responsible for producing most of the energy (ATP) that the cell needs to carry out its functions. This is done through a process called cellular respiration, which takes place within the mitochondria. The mitochondria also plays a key role in other cellular processes, such as apoptosis (programmed cell death), calcium signaling, and the synthesis of certain important molecules.
