Relate Mitochondria organelles with eukaryotic cells

Mitochondria are highly specialised organelles in eukaryotic cells. These perform the energy transducing process, and are often referred to as the "power houses" of the cell. Mitochondria are the largest organelles in a cell with a diameter of 0.5 - 1µm, and their numbers vary from one cell type to another. The rat liver cell for instance, has about 800 mitochondria, which occupy nearly 25% of the total cell volume. Mitochondria are of different shapes, e.g., spherical in the liver cells, cylindrical in the kidney cells or thread like in fibroblasts, and in some cells namely yeasts, are even highly branched. Within the cell, mitochondria are frequently found to be located in regions where there is a high demand for ATP.
