Cards (1)

  • Effect of osmosis on plant tissue
    1. Peel vegetable
    2. Use a cork borer to produce three cylenders of potato
    3. Use a scalpel to trim cylinders to the same length (around 3cm)
    4. Measure length with a cuter and Mass with a balence
    5. Place each cylinder into a test tube
    6. Add 10cm³ of 0.5 molar Sugar solution to the first test tube
    7. Add 10cm³ of 0.25 molar Sugar solution to the 3rd test tube
    8. Add 10cm² of distilled water to the third test tube
    9. Leave overnight allows osmosis to take place
    10. Remove potato cylinders and role on paper towels remove fre
    11. Measure length and mass of cylenders again
    12. Calculate percentage change = change in value/Original value x 100
