Two methods were used that involved soaking a plant to determine its water potential. The method using a balance has the advantage of producing very quantified results with high sensitivity, whereas the Chardakov method does not require any technical equipment. If a researcher performs a tissue analysis ( tissues are all the same size) using both methods, but the lack of equipment does a poor job of standarizing the volume of the sucrose solution between the different treatments. How will this impact the results for each method?

Solution

Both the methods will be based on measuring the changes in density of the sucrose solution that will take place after the plant tissues are soaked in it.Depending on the water potential of the tissue,the sucrose solution will either lose or gain water. If there is no change in density of the sucrose solution,it means that there is no net movement of water and it can be concluded that the solution has the same water potential as the tissues that were incubated in it. A change in density of sucrose solution i.e either increase or decrease will give a clue to the water potential of the plant tissues.Density is mass/volume.Density will depend on the volume of the solution.If we do not standardise the volume of the sucrose solution , we will not be able to know the exact density changes in the sucrose solution for each method and cannot compare the results accurately.
