Aim The aim is to find the concentration (mole/dm3 (M)) of solute in a spud cell by using the process of osmosis and diverse concentrations of saccharose source. Background information Osmosis is diffusion of wet crosswise a part semi pervious membrane. It moves from a re establish with less solute concentration (high water system potential) to a solution with practically 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 fount of concentration is on the different array of the partially porous membrane. When more water passes with with(predicate) to one stance of the membrane it is called salary movement. (Toole + Toole Essential AS level biological science) This is an workout of the earnings movement through a partially leaky membrane. The pay off side is the more thin out solution, whi ch makes it the hypotonic solution. The left side is the less hack solution, which makes it the hypertonic solution. mesh topology movement occurs through the more foreshorten 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 solidness lines show the level of the two sides after(prenominal) it was left for 2 hours. The right side has more s olution in it because of the greater net mov! ement of water going to the right from the left side by the process of osmosis. (Marveen GCSE Biology) This diagram is of two liquids confused by a partially permeable membrane. The left side has large molecules of solute that has dissolved...
