1.1. Design an experiment to estimate the glucose concentration of the cell contents of sweet potato tuber. The following equipment has been provided. 

• Sweet potato

• 1 mol dm³ glucose solution

• Cork borers

• Other common laboratory supplies and reagents.

Outline the steps you would take and the way that you would process the data that you would generate. 

1.2. Sketch a graph of the expected results from the experiment in question 3a). 

1.3. Define the term, ‘water potential’ and explain why values of water potential are expressed in kilopascals (kPa).

1.4. Explain why an aqueous solution has a lower water potential than pure water.
