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.
Word origin: Iridium comes from the Latin word iris, meaning rainbow. Discovery: British chemist Smithson Tennant discovered iridium in the residue left when crude platinum is dissolved by aqua regia in 1803. Properties of iridium. Iridium is the most corrosive resistant metal known and one of the densest metals.It is a member of the platinum family and is white with a yellowish tinge.
