Final answer:
Sperm and muscle cells have large numbers of mitochondria to support their energy-demanding functions.
Explanation:
Sperm cells and muscle cells require a lot of energy, which is primarily produced in mitochondria. Mitochondria are known as the powerhouses of the cell.
Smooth muscle cells and sperm cells have a high concentration of mitochondria to support their energy-demanding functions. Smooth muscle cells need energy for contraction, while sperm cells utilize energy for motility.
Both sperm cells and muscle cells have a high number of mitochondria due to their high energy requirements. Mitochondria play a crucial role in providing the necessary ATP for functions such as muscle contraction and sperm motility.
