osmosis

The aim of this experiment is to investigate the movement of water into and out of plant cells by osmosis. The cells chosen for study will be taken from potato tubers as they provide a ready supply of uniform material. Any substance dissolved in water is called a solute; a solvent is a liquid that is able to dissolve another substance, called a solute, to form a solution. The water content of plants varies depending …

…potato tubes a further experiment was carried out. Six tubes were placed in distilled water at 20°C and another six in distilled water at 50°C. Change in mass was recorded every half hour for four hours. If time permits I will narrow my range of molarities down to 0.1 increments around the point where there appears to be least change in mass in an attempt to determine the precise molarity of the potato tuber cell vacuoles.
