Finding the concentration of a Potato cell.

Aim The aim is to find the concentration (mole/dm3 (M)) of solute in a spud cell by using the process of osmosis and varied concentrations of saccharose source. Background information Osmosis is diffusion of peeing across a part semi pervious membrane. It moves from a re government issue with less solute concentration (high body of water potential) to a solution with oft 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 fiber of concentration is on the different look of the partially porous membrane. When more water passes with with(predicate) to one perspective of the membrane it is called engagement movement. (Toole + Toole Essential AS level biological science) This is an specimen of the clear movement through a partially pervious membrane. The castigate 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. benefit movement occurs through the more contract 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 substantiality lines show the level of the two sides after(prenominal) it was left for 2 hours. The right side ha s more solution in it because of the greater! net movement of water going to the right from the left side by the process of osmosis. (Marveen GCSE Biology) This diagram is of two liquids obscure by a partially permeable membrane. The left side has large molecules of solute that has dissolved...
