Mitochondrion because they are responsible for producing energy
The mitochondria is the organelle responsible for producing energy. Because the heart is the strongest muscle in the body, and it works constantly, it would make sense for heart muscle cells to have more mitochondria. Nerve cells send electrical impulses to various parts of the body, but, comparatively, they don't need as much energy.
The cells are alive and metabolically active.
Cells that require a lot of energy, such as muscle cells or cells in the heart, would likely have the most mitochondria.
Cells that are specialized for specific functions, such as nerve cells and muscle cells, would most prefer not to have cells undergoing division.
Mitochondria is the part of cells that generate energy by turning nutrients and oxygen into fuel for the body. Muscle cells need this ability more because they are constantly working; fat cells do not need it as much.
Mitochondria
Mitochondria - to produce the ATP needed for muscle contraction
Mitochondria as the heart requires a lot of energy.
The organelle which is more abundant in muscle cells than in other cells is mitochondria. This is due to the fact that muscle cells require more energy than any other cells.
The only organelle that is unique to animal cells is the centriole.

Muscle cells.
mitochondria
The answer is mitochondria. Athletes have more muscles, therefore more mitochondria, which are abundant in muscle cells.Also see: What_organelle_do_athletes_have_more_of_than_sedentary_individuals
Chloroplast
In Eukaryotic cells it would be the nucleus.
Of course in muscle cells.They are very active cells
