Mitochondria are important because without them working very well, you die. They are the power plants in living cells. Mitochondrion >From Wikipedia, the free encyclopedia Jump to: navigation, search In cell biology, a mitochondrion (plural mitochondria) (from Greek mitos thread + khondrion granule) is an organelle, variants of which are found in most eukaryotic cells[1][1]. Mitochondria are sometimes described as "cellular power plants," because their primary function is to convert organic materials into energy in the form of ATP via the process of oxidative phosphorylation. Usually a cell has hundreds or thousands of mitochondria, which can occupy up to 25% of the cell's cytoplasm. Mitochondria usually have their own DNA and are accepted by Endosymbiotic theory to have descended from once free-living bacteria[2], that were closely related to rickettsia bacteria. James A.

So, about the genome, what is it all for? Well, there is all kinds of evidence to suggest that animals are optimizing the size of their cells whereas parasites often minimize the amount of junk in their genome. The reason I'm mentioning any of this is because Dr. Mike mentioned the good ole mitriochonria which is a term most of you have heard but not as much is known about it except why would we need two sets of DNA. The mitriochonria resides in the cells separate from the other DNA and is passed along by mothers so we can trace the maternal line using it, although that is not what it's real purpose - so what is it really for Dr. Mike? Well, some think it is some old bacteria and what we are seeing really is the DNA for a bacteria in the organelles in our cells (every one of them). But, what is it for? Dr. Mike, why don't you complete the sentence, "Mitriochonria is important because....."
