* 40% sugar solution when the potato was placed into it and the mass was measured from time 5 minutes the mass was low then decreased greatly at a faster pace from time 10 minutes to 25 minutes * From time 60% the mass of the potato was low at time 5minutes which kept decreasing sharply from time 10 minutes to 25 minutes 4. Identify and suggest reasons for any anomalies (if none write “none) An anomaly will be that when the mass of the potato was measured for 6% of sugar solution, the mass at time 5minutes was high then it decreased sharply at times 10 minutes to time 20 minutes this shows that the pressure with which the potato shrunk made the potato less rigid which made the cell membrane of the potato start shrink from the cell itself therefore causing the mass to decrease, also from 20% to 60% of sugar solution was used the mass of the potato decreased sharply as time went on which also shows that the cell membrane of the potato has plasmolysed which shows that the cell membrane has pulled away from the cell which shows with the shrinkage of the potato. 5. Explain the trends observed in the group’s data: The trends showed that with distilled water the mass increased within a time range which showed that osmosis was taking place so the cell were rigid and the weight of the potato increased then it started decreasing in mass which shows that it started losing water but then after 25mins it regained its rigidity by absorbing more
