Which organelle is known as the powerhouse of the cell?

The mitochondria are known as the powerhouse of the cell because they are responsible for producing adenosine triphosphate (ATP), which is the primary source of energy for cellular processes. Through a process called cellular respiration, mitochondria convert nutrients into ATP, mainly utilizing oxygen and glucose. This energy production is crucial for various cellular functions, including metabolism, muscle contraction, and nerve impulse transmission.

In addition to energy production, mitochondria also play a role in other vital cellular processes, such as the regulation of the cell cycle and cell growth. They are involved in the apoptosis process, which helps in eliminating damaged or unnecessary cells, ensuring the overall health and functionality of the organism.

Understanding the importance of mitochondria highlights why they are labeled the powerhouse of the cell, emphasizing their central role in maintaining energy levels necessary for life.
