The role of mitochondria is to supply energy to the cells
Which is which is why the answer is A. The powerhouse of the cell
Mithochondria can transfrom oxygen to generate energy for the cell. For example, brain cells in our brain need a lot of energy to process all the information what we inputted, thats when mitochondria took part.
