3.1 BIOLOGICAL MEMBRANES 3.1.1 Properties of Cell Membranes • Separates living cell from its nonliving surroundings. • 8 nm thick. • Selectively permeable - allows some substances to cross more easily than others. 4.1.2 Fluid Mosaic Model • Singer and Nicolson (1972) - plasma membrane is a mosaic of proteins dispersed within lipid bilayer‚ with only bilayer‚ the hydrophilic regions exposed to water. Hydrophilic region of protein Phospholipid bilayer Hydrophobic region of protein

Synopsis – Grade 9 Science Term II Chapter 1: Atoms and Molecules Law of conservation of mass: Mass can neither be created nor can it be destroyed in a chemical reaction. Law of constant proportion: A chemical substance always contains the same elements in a fixed proportion by mass‚ irrespective of the source of compound. Atom: The smallest particle which is the building block of matter. The symbol of the element is made from one or two letters of the English
