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.
Red blood cells of birds have a nucelus, and have DNA. Mature mammalian red blood cells do not have a nucleus, but they must still have mitochondria, otherwise they can not generate their ATP. Mitochondria are independent of the host cell.est Answer: No, red blood cells do not have and do not need a nucleus (except for when they are developing in the bone marrow). This maximises the space available for haemoglobin, and so allows them to transport oxygen more efficiently.
