Statement 2 is false: this is because the number of mitochondria will correspond to the energy demand of the cells. The number of mitochondria can vary depending on the metabolic activity and specific function of the cells. The muscle cells or cells involved in active transport, tend to have a higher number of mitochondria to meet their energy needs
