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.
Iridium is very hard and brittle and hardens other metals it is alloyed with, especially platinum. These alloys are used in spark plugs, electrical contacts, and high temperature crucibles. Biological Rating: No known benefits for life processes in plants or animals.btained From: Iridium is found in its pure native form and in osmiridium, a natural alloy of iridium and osmium. Iridium is mined from sulfide layers in mafic igneous rocks where it is present with other platinum-group elements.
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.he most stable of these is 192m2 Ir, which decays by isomeric transition with a half-life of 241 years, making it more stable than any of iridium's synthetic isotopes in their ground states. The least stable isomer is 190m3 Ir with a half-life of only 2 Âµs.
