When cells divide, they make new cells. A single cell divides to make two cells and these two cells then divide to make four cells, and so on. We call this process cell division and cell reproduction, because new cells are formed when old cells divide. The ability of cells to divide is unique for living organisms.
You see, mature red blood cells don't grow, they don't divide, and they don't make any new proteins. If a cell doesn't make new proteins or divide, it also doesn't need ribosomes to translate RNA into proteins, and it doesn't need DNA for transcription or replication, which makes DNA and the nucleus unnecessary.Red blood cells also use very little energy, which makes the mitochondria unnecessary.fter all, red blood cells have to come from somewhere, and cells do need mitochondria and a nucleus with DNA to go through mitosis, make new cells, and make all of that hemoglobin protein. As it turns out, immature red blood cells do have mitochondria and a nucleus for just those reasons.
