Final answer:
If an animal cell's mitochondria were unable to function, it would not be able to make its own food.
Step-by-step explanation:
If an animal cell's mitochondria were unable to function, it would have a significant impact on the cell system as a whole. The mitochondria are responsible for producing energy in the form of ATP through cellular respiration. Without functional mitochondria, the cell would not be able to generate enough energy to carry out essential processes.
This would mean that option A: The cell would not be able to make its own food is the correct answer. Mitochondria play a crucial role in generating energy for the cell, which is necessary for processes such as photosynthesis in plant cells or obtaining nutrients in animal cells. Without functional mitochondria, the cell would not be able to produce the energy required to produce food.
