Evolutionary biology: Essence of mitochondria
Katrin Henze1 & William Martin1
Abstract
For years, a unicellular creature called Giardia has occupied a special place in biology because it was thought to lack mitochondria. But it does have them — though tiny, they pack a surprising anaerobic punch.
All known life-forms are either prokaryotes or eukaryotes; there is nothing in between. Eukaryotic cells have a nucleus and compartments that are surrounded by two membranes, but prokaryotic cells never do.
