All forms of striated muscles have multiple mitochondria. This includes skeletal muscle and cardiac muscle. While each muscle can be considered an organ, the answer that is most likely to be correct is the heart.
Fun fact: Skeletal muscles not only have a lot of mitochondria, they are also multi-nucleated. Each muscle cell, also called a fiber, can have 2, 3 or more nuclei.
Yes, mitochondria are found in the cells of all eukaryotic organisms, including dogs. Mitochondria are known as the powerhouses of the cell because they generate energy in the form of ATP through cellular respiration.
The Proximal Convoluted Tubule
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
In the Mitochondria
You would expect to find a large number of mitochondria in an eukaryotic cell that needs to produce a large amount of ATP. Mitochondria are the powerhouses of the cell and are responsible for producing ATP through cellular respiration. They are abundant in cells with high energy demands, such as muscle cells.
Mitochondria exists in every cell. It is an organelle, an organ of a cell.
Cells with more mitochondria are typically found in tissues that require a lot of energy, such as muscle cells and liver cells.
in a plant
You would often find the barrel organ being played in churches.
Skin is the largest organ of the body and also has the most nerve endings.
You would expect to find a high concentration of mitochondria in cells that require a lot of energy, such as muscle cells and nerve cells.
MITOCHONDRIA
In the cytoplasm of eukaryotic cells.
organism describes the entire individual, a human, just like it would describe a fish. However, "in" the human body, one would find SYSTEMS such as the digestive and nervous systems.
lung
The body is made up of millions of cells. These cells form tissue, which in turn forms organs, then organ systems (what makes up people). To see a cell, you would have to view it under a microscope.
Mitochondria is a cite in the cytoplasm also known as power house of the cell because of their energy generating ability in the cell. In humans there are many life activities that goes on in the body in order to make life possible. The prominent activity is that needs large amount of energy is reproduction. This occurs in the tissues, hence mitochondria are mostly found in muscle tissues for this life activity.
