Cytoplasm can be divided into: Cytosol, organelles and cytoplasmic inclusions. Cytosol is a gelatinous material and most of the space in cytoplasm when an organelle is not present. Cytosol comprises of salt, water, cytoskeleton filaments and organic molecules.he cytoplasm and the enzymes within it break down the macromolecules into small portions to facilitate energy production for the mitochondriaâs of all the cells. Cytoplasm plays an important role in the process of glycolysis as well as in the synthesis of fatty acids, amino acid and sugar.
A very hard, brittle, silvery-white transition metal of the platinum group, iridium is generally credited with being the second densest element (after osmium) based on measured density, although calculations involving the space lattices of the elements show that iridium is denser.ridium is one of the rarest elements in Earth's crust, with annual production and consumption of only three tonnes. 191 Ir and 193 Ir are the only two naturally occurring isotopes of iridium, as well as the only stable isotopes; the latter is the more abundant of the two.
It can be made in a laboratory by the reaction of sodium with chlorine. However, it is found naturally in large amounts in sea water or in underground deposits. It is often obtained either by evaporating sea water or by mining underground deposits.ining. Salt can be mined as rock salt which is used to treat icy roads in the winter. It lowers the melting point of the ice on the roads so that it melts, even when the temperature is below 0ÂºC. Salt can also be mined by solution mining.
