chromosomes mitochondria nuclei vacuoles
I gave my students this multiple choice question: Muscle cells need to quickly convert energy from food molecules into a usable form. For this reason, which of the following do muscle cells have in greater numbers than most other types of cells?

Only one answer is correct among these 4 choices:
- chromosomes
- mitochondria
- nuclei
- vacuoles

Could you tell me which one is correct?

mitochondria
