Biology Osmosis Finding the osmotic pressure of potato cells Osmosis is the passing of water molecules from a weaker solution (high water concentration) to a strong solution (low water concentration) across a semi- permeable membrane. A potato is a prime example of osmosis. A potato is a root vegetable. They take water in for the plant to photosynthesise. 6C02+6H2O C6H12O6+6O2 The water swells the vacuole without mis-shaping the cell due to the rigid cell wall. When it has become swollen, it is called a 'turgid' cell. When it is without swelling, it is called a 'flaccid' cell. (Diagram of osmosis) Molarity is 'relative molecular mass' in grams, dissolved in 1Dm ,or one decimetre. The molarity of sucrose: C6H12O6 12 x C= 12 x 12= 144 22 x H= 22 x 1 = 22 11 x O= 11 x 16= 176 = 342 The molarity of sucrose is 324g in one decimetre. My experiment aims to find the osmotic pressure of potato cells. This...
