Osmosis in Potato

Aim: The purpose of this laboratory is to investigate the relationship mingled with solute niggardness and the movement of weewee done a selectively porous membrane by the work of osmosis. Hypothesis : my supposal is that the snowy white white white tater vine result shrink in sizing because when you repose the white potato in the scared upshots the water liable(predicate) immaterial the potato depart be less than the water potential inside the potato therefore , the potato provide shrink. Variables : 1.Independent : concentration of the solution 2.Dependent : softwood of the potato 3. Controlled variable: Temperature The hail of the solution Materials : 1.4 beakers ( atomic number 6ml) 2. potato 3.knife 4.cork ( size 2) 5.ruler 6.
