Summary:
Provides the details of an experiment with the aim of finding out the effect of different concentrations of sucrose solution on potato cell samples. Describes the process of osmosis. Presents the hypothesis that as the concentration of sucrose increases that the size of the potato segment will decrease.
Aim- to find out the effect of different concentrations of sucrose solution on potato cell samples
Background knowledge
Process of Osmosis
In osmosis, a solvent (often water) moves from a region of low concentration to a region of high concentration through a semi-permeable membrane. Here, water molecules diffuse into the concentrated sugar solution because the water molecules are small enough to move through the membrane. The larger sugar molecules are unable to move through the membrane into the water solution. Osmosis will stop when the two solutions reach equal concentrations on either side of the membrane.
Sucrose, a sugar with the formula C12H22O11, belonging to the group of carbohydrates known as disaccharides. It is ordinary table sugar, extracted from sugar beet or sugar cane. It is soluble in water, slightly soluble in alcohol and ether, crystallizes in long,.....
