(ii) A Petri dish contained sugar solution and the cavity in the potato contained distilled water. Observation: The volume of distilled water in the potato cavity would decrease. Explanation: The sugar solution in the Petri dish has a lower water potential than the distilled water in the potato cavity. Water molecules would move by osmosis from the distilled water (higher water potential) out of the potato cavity, through the potato cells, and into the sugar solution in the Petri dish. The potato tissue would become flaccid.
