Question

For plant physiology, We employed two methods that involve soaking a plant tissue in order 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 and is therefore very useful in the field.  Let’s say that a researcher performs a tissue analysis using each of these methods but, because of a lack of equipment, does a poor job of standardizing the volume of the sucrose solution between the different treatments (the tissue samples, however, are all of the same dimensions).  How is this likely to impact the results in each case?

Explanation / Answer

The total volume of sucrose solution is bound to effect the total concentration of sucrose which certainly effects the water potential, movement of water and thus turgid or shrink state of the plant cell.
