- Aim: To investigate the range of concentrations of salt or sugar solutions on the mass of plant tissue
- You will:
- Prepare samples of potato and place them in different concentrations of sugar or sodium chloride (salt) solution
- Make measurements of mass and length of your samples before and after soaking them in solutions
- Calculate the percentage change in mass of plant tissue
- Plot, draw and interpret appropriate graphs
- In this practical, you should take care to prepare your samples of potato carefully and record your measurements accurately
- This practical can be carried out with either salt or sucrose solutions of at least five different concentrations
- The length of time that the potato cylinders are left will vary
- This experiment can be carried out in a water bath at $30^{\circ} \mathrm{C}$ in 30 minutes
