Answer :

Final answer:

Mitochondria are organelles that produce ATP through cellular respiration, serving as energy powerhouses for cells.


Explanation:

Mitochondria are organelles responsible for producing ATP, the cell's main energy-carrying molecule, through a process known as cellular respiration. They have double membranes, with the inner membrane highly folded into structures called cristae to increase surface area for ATP production. Mitochondria play a vital role in providing energy for various cellular functions such as muscle contraction and nerve cell operation.
