Investigation to look at the water potential of Celeriac A-S Coursework Transport Module Joel Davies The aim of this investigation is to look discover the water potential of the root vegetable Celeriac. To do so, the effect of varying concentrations of sugar solutions on Celeriac will be observed and a conclusion reached. As preliminary work, the effects of sugar solution on potato has been investigated to give a general idea of what to expect and to discover any problems with the, method before the larger Celeriac experiment. Background research has also highlighted properties of Celeriac that are different to potato and will therefore affect the water potential of the plant. Relevant background knowledge The generalised plant cell is as in the diagram below: The vacuole and cytoplasm contain the solution that is being investigated. The cell wall is fully permeable and therefore does not effect the movement of substances into and out of the cell. It...
