Final answer:
The mitochondria in cells function to produce energy through cellular respiration.
Step-by-step explanation:
The function of mitochondria in cells is to produce energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration. Mitochondria are often referred to as the 'powerhouses' of the cell because they produce the energy needed for various cellular activities. They have their own DNA and can divide independently within the cell. Mitochondria are found in most eukaryotic cells, including animal and plant cells.
