nucleus and vacule {they are types of cells}
The muscle cell
Muscle tissue and liver both have a lot of mitochondria: muscle tissue because it has to release a lot of energy for movement, and liver because it takes a lot of energy to process and eliminate toxins from the body.
Musle
In Very active cells like skeletal muscle cells,cardiac muscle cells
Muscle tissue specializes in contraction. This includes cardiac, smooth, and striated.
Very active cells have many mitochondria.Examples are cardiac cells,muscle cells etc.
mitochondria
Mitochondria are the power-houses of every cell in your body (and all animals!). Inside these organelles the magic of respiration occurs through a process known as the "Krebs" cycle. Cells that use a lot of energy have the most mitochondria, most notably those that make up muscle, and any cell that divides frequently (such as basal cells in your skin). The body never puts the power-plant too far away from where it's needed, except in the case of nerve cells- These little guys use a TON of energy, but rely on other support cells to produce it! And you would find the most mitochondria in the muscle
