Osmosis — practice question

A potato was chosen as the source of plant tissue. Four potato sticks of the same size were cut from the same potato. At the beginning of the investigation, each potato stick measured $10$ squares in length. The potato sticks were placed in four separate Petri dishes. Each Petri dish held a different concentration of sugar solution. The diagram shows the four Petri dishes after $24$ hours. Which dish contains a sugar solution with a higher water potential than the potato tissue?
