Mitochondria. Transmission electron micrograph of mitochondria from mammalian tissue culture cells, showing the double outer membranes and numerous internal membranes (cristae) where respiration takes place. Mitochondria provide cells with energy by oxidising sugars and fats. They are found in almost all cells, have their own DNA (deoxyribonucleic acid), and replicate autonomously. Magnification x153,900 at 10x8 inch size.
