Osmosis investigationaim:the aim of this experiment is to investigate the effect of changing theconcentration when the potato is put in sucrose concentration where the waterpotential is greater than that of the same set temp for each investigation performed by using athermometer to monitortype of record. Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration when a potato is placed in water, the cells will expand by gaining weight depending on the concentration levels of the solution when the concentration of the water is. Assessment has been introduced as part of nearly all new gcses, to replace coursework control levels are set for each of the controlled assessment processes: task setting, task taking and task marking for each stage, the level of control will ensure reliability and authenticity, and make assessments more. Free essay: with the potato in molar solutions of sucrose, i do not think there will be much change in the weight of the potato this is because there is not. Specifically, i intend to use my knowledge of osmosis to investigate the glucose concentration of the cell sap in potato cells osmosis is a method by which water levels on either side of a semi permeable membrane may balance themselves it occurs between regions of high water concentration and low water concentration.
