Mitochondria is the only organelle other than the nucleus that contains its own DNA (genome). It is also the organelle which produces the most ATP (adenosine triphosphate), which is the necessary power molecule for carrying out the cells chemical reactions.

Some characteristics of mitochondria that distinguish them from other organelles (and also suggest that they were once free-living bacteria) are that they have two membranes, an outer membrane and an inner folded membrane (seen in bacteria), it has its OWN DNA, different than that of the organism, mitochondrial chromosomes are circular and attached to the membrane (seen in bacteria), it has unique ribosomes, of the size and density unique to bacterial ribosomes, and it provides the ATP that the cell needs for energy.

There are cristea inside of organelle to increase surface area. They are also the cells that produce ATP, and are sometimes called the "fuel" or "engine" of the cell.
These cells also have two distinctive membranes

Mitochondria have two membranes and their own DNA, RNA and ribosomes. Plastids (chloroplast, chromoplast) also have the same properties. So both mitochondria and plastids are believed to have derived from symbiotic bacteria.

They contain the organism's DNA.
