Basic chemistry of a cell Properties of water – – – Life on Earth began in water and evolved there for 3 billion years before spreading onto land. Modern life‚ even terrestrial life‚ remains tied to water. All living organisms require water more than any other substance. Human beings for example‚ can survive for quite for a few weeks without food‚ but only a week or so without water. – – – Water is deceptively simple. It is shaped something like a wide V‚ with its two hydrogen atoms joined

OSMOSIS Aim To determine the water potential of potato tuber cells. Background knowledge Osmosis is defined as the movement of water molecules from a region of higher water potential to a region of lower water potential through a partially permeable membrane. Osmosis is considered in terms of water potential and solute potential. Water potential is a measure of the kinetic energy of water molecules. Here‚ water molecules are constantly moving in a random fashion. Some of them collides with cell
