Detailed explanation-1: -Mitochondria are the part of the cell that produces ATP which the cell can then use as energy to do work. Muscle cells require a lot of ATP to carry out contraction and therefore a large number of mitochondria are required to produce this ATP.
Detailed explanation-2: -Mitochondria: the energy converters Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria.
Detailed explanation-3: -For example, heart muscle cells have a lot of mitochondria as our hearts need a constant supply of energy to keep pumping. Sperm cells also have a lot of mitochondria as they need a lot of energy to be able to swim towards an egg cell for fertilisation.
