Aim The aim is to find the concentration (mole/dm3 (M)) of solute in a spud cell by using the process of osmosis and contrastive concentrations of saccharose source. Background information Osmosis is diffusion of water system system across a part semi semipermeable membrane. It moves from a re exertion with less solute concentration (high water potential) to a solution with much solute concentration (low water potential). The one with a high water concentration is called a hypotonic solution and the low water concentration is called hypertonic solution, but these lonesome(prenominal) depend on what quality of concentration is on the different human face of the partially permeable membrane. When more water passes with with(predicate) to one stead of the membrane it is called realize movement. (Toole + Toole Essential AS level biological science) This is an cause of the moolah movement through a partially permeable membrane. The just side is the more thin out s olution, which makes it the hypotonic solution. The left side is the less hack solution, which makes it the hypertonic solution. crystallise movement occurs through the more elongate to the less dilute so it goes from left to right though the partially permeable membrane.
As you can see, the dotted tune liberation horizontally through the middle of the two levels of solution shows the level of the solutions at the beginning when the two sides where given come to amounts of its solution. The horizontal whole lines show the level of the two sides after(prenominal) it was left for 2 hours. The right side has more solution in it because of the greater net movement o! f water going to the right from the left side by the process of osmosis. (Marveen GCSE Biology) This diagram is of two liquids spaced by a partially permeable membrane. The left side has large molecules of solute that has dissolved...
