The intracellular fluid of inside a cell called the cytosol. It is separate from certain cell organelles such as the nucleus and the mitochondria. In eukaryotes, the cytoplasm is the content within a cell membrane minus the content in the cell nucleus.n the other hand, cells such as eukaryotes cell the cytosol containing the cell's genome is held within the cell nucleus, which then separates from the cytosol by nuclear pores that blocks the free diffusion of any kind of molecule that is larger than 10 nm in diameter.

Iron Iron is a trace mineral needed to make hemoglobin, the protein needed to carry oxygen throughout the body. Hemoglobin gives red blood cells their color, and stores most of the body s iron supply.Iron is also stored in muscle tissue, and helps supply the muscles with the oxygen needed to make them contract.Although iron is a trace mineral, it is extremely important, because a deficiency in this nutrient leads to a shortage of red blood cells, a condition known as anemia.Anemic individuals do not have an adequate supply of oxygen in their body, which leaves them tired, pale, and short of breath.ron is also stored in muscle tissue, and helps supply the muscles with the oxygen needed to make them contract.
