A tomato by itself wouldn't ahve any voltage.
But it's kinda acidit so if you stuck say a piece of copper and a piece of zinc in it, it'd act as a crude battery and you'd probably get a voltage.
Potato chips are solids.
Starch is not a solution.
Dividing the potato tuber into six discs allows for multiple replicates to be tested for each water potential solution, increasing the reliability of the results. It also ensures that any variations in the samples can be accounted for, providing a more accurate representation of the water potential of the potato tuber cells.
When a potato is placed in a salt solution, osmosis occurs. Water molecules move from an area of higher concentration (inside the potato) to an area of lower concentration (the salt solution), causing the potato to lose water and shrink. This demonstrates the process of osmosis, where water moves across a semi-permeable membrane to balance the concentration of solutes on both sides.
This is because the potato, which is mostly water, is in a hypertonic solution (a solution with less water and more solute --here, sucrose-- than the potato). Since the solutions want to reach equilibrium (equal amounts of sucrose and water in both the solution and the potato), water diffuses out of the potato and sucrose diffuses into it. The potato loses its water weight, and sucrose doesn't replace the weight lost, the potato weighs less.
This depends on the concentration of the salt solution. If the water potential of the salt solution is greater (less concentrated) than the cell sap of the potato cells, water would move into the potato cells, increasing the size of the potato strip. If the water potential of the salt solution is lower (more concentrated) than the cell sap of the potato cells, water would move out of the potato cells in the salt solution, decreasing the size of the potato strip.

Because of osmosis the water in the potato will move into the hypertonic solution causing the potato to lose weight.
When a potato is placed in a concentrated sugar solution, water will move out of the potato cells via osmosis, resulting in the potato shrinking and becoming soft and limp. This is because the sugar solution has a higher solute concentration than the potato cells, causing water to move from an area of higher water concentration (inside the potato) to an area of lower water concentration (the sugar solution).
In the concentrated sugar solution, water will move out of the potato cube, causing it to shrink due to osmosis. In distilled water, water will move into the potato cube, causing it to swell due to osmosis.
This is because the potato, which is mostly water, is in a hypertonic solution (a solution with less water and more solute --here, sucrose-- than the potato). Since the solutions want to reach equilibrium (equal amounts of sucrose and water in both the solution and the potato), water diffuses out of the potato and sucrose diffuses into it. The potato loses its water weight, and sucrose doesn't replace the weight lost, the potato weighs less.
A 0.9% sodium chloride solution (normal saline) is more likely to be isotonic to the intracellular fluids of a potato. This concentration is similar to the overall solute concentration inside the cells of a potato, making it the best choice to prevent osmotic imbalance when the potato is immersed in the solution.
