Some parasitic protists, for example, take energy from their hosts and do not have mitochondria, as explained by an article in the Journal of Eukaryotic Microbiology. In humans, mature red blood cells, or erythrocytes, lack mitochondria as well, as reported by the Encyclopedia Britannica.

A woman scientist first suggested all this, Lynn Margulis.he best story we have now is that mitochondria are actually the descendants of bacteria that hitched a ride in larger, more complex cells. Our cells, and those of plants, amoeba-type things, and fungi, are eukaryotic..
