Eukaryotic Exceptions. Most eukaryotic cells -- those that contain nuclei -- also contain mitochondria, but there are exceptions to this rule. 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.
After all, every cell in your body (except mature red blood cell, which have no nuclei, and egg cells) has the same DNA in its nucleus. Why would mitochondria need. The 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.. Bacterial cells are called prokaryotic.. They don't have nuclei, they are much smaller than our cells, and don't have organelles like our cells. Perhaps the tiny prokaryotes invaded early eukaryotes a long time ago (like 1.4 billion years ago) in order to absorb their food, acting like parasites.
