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.
Neodymium is never found in nature as a free element, but rather it occurs in ores such as monazite and bastnÃ¤site that contain small amounts of all the rare earth metals. The main mining areas are in China, the United States, Brazil, India, Sri Lanka, and Australia.
