Final answer:
The mitochondria is the "powerhouse" of the cell, producing energy in the form of ATP through cellular respiration.
Step-by-step explanation:
The mitochondria is considered as the "powerhouse" of the cell because it is responsible for producing the majority of the cell's energy in the form of ATP (adenosine triphosphate).
It does this through a process called cellular respiration, in which glucose and oxygen are converted into ATP through a series of biochemical reactions.
This energy is then used by the cell to carry out various functions, such as muscle contraction, cell division, and active transport.
