... Investigating the cellular water potential of potato cells. Aim: - to determine the water potential of potato cells by using different concentrations of sucrose solution. Introduction:- Water potential is the tendency of water molecules to move from one place to another, water potential can also be represented by the Greek letter psi, ?. The water potential for pure water is 0. This is because there is no tendency of the water molecules to move. The movement of water molecules almost always tends to be from a region of high water potential to a region of lower water potential. This is down the water potential gradient. Water potential can be affected by various factors, such as the amount of solute that is in the solution and the pressure that is being exerted. Solute potential (?s) is the amount by which the solute molecules lower the water potential of a solution. As the solute decreases the water
