Mitochondria
It ranges in size from 0.5 to 1.0 micrometer (μm). Some cells have only one and some have more than one mitochondria in them. It has different compartments and two membranes, outer and inner with intermembrane space in between. The inner membrane is in the form of folds forming shelves which increase the surface area. Although most of the cellular DNA is present in the nucleus, mitochondrion has its own DNA. The major function of the mitochondria is to provide the cell with energy in the form of ATP (adenosine triphosphate). It is also involved in other cellular functions such as cell growth, signaling and cell death. It also plays a role in the process of aging.
