Question

(c) A student conducted an experiment to investigate the percentage change in mass of potato tuber tissue when placed in different concentrations of sucrose solution. The potato tuber tissue cut into cubes of the same size. Fig. 4.2 shows a graph of the results. 40 30 20 10 percentage change 0 in mass 0.0 -10 0.2 0.4 0.6 1 0.8 1.0 -20 -30 -40 concentration of sucrose solution/moldm3 (i) Use Fig.4.2 to predict the percentage change in mass of a cube of potato tuber tissue plac mol dm-3 sucrose solution. (ii) Explain the results shown in Fig. 4.2 in terms of water potential: • between sucrose concentrations of 0.0 -0.4 mol dm-3 • at sucrose concentration 0.4 mol dm-3 between sucrose concentrations of 0.4 - 1.0 mol dm-3. Between 0.0 -0.4 mol dm-3 AL04 mol dm-3​​
