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.
History and Uses: Osmium and iridium were discovered at the same time by the British chemist Smithson Tennant in 1803. Osmium and iridium were identified in the black residue remaining after dissolving platinum ore with aqua regia, a mixture of 25% nitric acid (HNO 3) and 75% hydrochloric acid (HCl).smium and iridium were discovered at the same time by the British chemist Smithson Tennant in 1803.
