... se or gain water molecules from another solution. A dilute solution, with its high proportion of free water molecules, is said to have a higher osmotic potential than a concentrated solution, because water will flow from the dilute to the concentrated solution (from a high to a low potential). Pure water has the highest possible osmotic potential because water molecules will flow from it to any other aqueous solution, no matter how dilute. The higher the water potential of the potato the less growth that can occur due to osmosis, this is because less water would flow into the potato. In general the osmotic potential of a potato is determined by a potatoes variety and the way the potato chips are prepared eg. washed, dried etc. The above information came from worksheets handed out in class, Microsoft encarta encyclopedia 98, and the CGP GCSE Biology revision guide. I have decided to further investigate the effects of the variables type of potato and length of time immersed in solution. I will investigate the potato types Nadine, Majorcan, New, ...
