Detailed explanation-1: -Different types of cells have different amounts of some organelles. For instance, cells that use a lot of energy tend to contain large numbers of mitochondria (the organelle responsible for harvesting energy from food). That’s why very active muscle cells are often full of mitochondria.

Detailed explanation-2: -What cells have the most mitochondria? A. Your heart muscle cells – with about 5, 000 mitochondria per cell. These cells need more energy, so they contain more mitochondria than any other organ in the body!

Detailed explanation-3: -For example, liver cells and muscle cells contain a lot of mitochondria. Muscle cells are assiciated with a large number of mitochondria as they require more ATP (energy) to function than other cells. They need this because of their frequent contraction and relaxation, which requires more ATP than average cells.

Detailed explanation-4: -Muscles cells contain more mitochondria because they have to release large amount of energy quickly for movement.
