Muscles require a high number of mitochondria within their cells to efficiently produce adenosine triphosphate (ATP), the primary energy currency of the cell. Mitochondria generate ATP through aerobic respiration, which is crucial during prolonged or intense physical activity. This energy production supports muscle contraction and endurance, allowing muscles to perform optimally and sustain activity over time. Additionally, more mitochondria enhance the muscle's ability to utilize oxygen and metabolize fats and carbohydrates for energy.
So that lots of ATP can be produced, which can then release energy for active transport. Remember that epithelial cell are cells that release substances and can take substances in (exocytosis and endocytosis). This requires energy, so there are therefore lots of mitochondria.
Animals with high energy demands, such as mammals and birds, tend to have cells with more mitochondria. These include muscle cells in athletes, brown fat cells in hibernating animals, and flight muscles in birds. Other examples are bees and butterflies, which need a lot of energy for flying.
Metabollically very active cells.As examples,cardiac,muscle cells.
hmm extracellular DNA perhaps? Eukaryotic cells however have lots of things prokaryote cells don't have like a nucleus and mitochondria.
If a cell has a relatively large number of, say, mitochondria (sites of respiration), than we know that it needs to release a lot of energy. This applies to the muscles, which have many mitochondria in order for them to contract. This helps us move. Cells where active transport occurs, such as the kidneys and small intestine, also need lots of mitochondria to give off the energy that is necessary for this to take place. You won't find as many mitochondria in a skin cell, because these don't need to carry out respiration.
Muscle cells are very active relatively to the skin cell. So it has more mitochondria
Muscles need ATP to contract. Mitochondria produce most of the ATP in the cell, so there are lots of mitochondria in muscle.
Mitochondria are the cell's power plant, producing ATP. Since muscles require a lot of ATP for contracting, lots of mitochondria are present in muscle cells (myocytes) in order to provide sufficient ATP
Lots.

Mitochondria convert the chemical energy in sugar to ATP which the actin-myosin need to contract. Without enough glucose, oxygen and the mitocondria to convert it to usable energy there can be no muscle contraction. Active muscle has many mitochondria so that the muscles appears darker.
Because muscles cells have to do more energetic work than other cells.
Muscle cells have lots of mitochondria. Mitochondria is known as a "powerhouse" of the cell. In the inner membrane matrix of the mitochondria there are ATP synthases that generate ATP energy.
Mitochondria would be the most common, because muscles are very active. They need the "powerhouses" so they can work with lots of energy and not get tired out. Hope this helped!! :D
Active cells such as muscle and liver cells have more mitochondria than others because they use up a lot more energy to carry out their roles and stay alive. Thus needing the extra mitochondria to produce more energy.
