Concept:Osmosis in plant cells depends on the relative salt concentration inside and outside the cell.Explanation:The plant cell has an internal salt concentration of about 3%.In solution III, the external concentration is 6% salt solution.Since 6%>3%, solution III is hypertonic compared with the cell contents.Water moves out of the cell by osmosis.The cytoplasm and cell membrane shrink away from the rigid cell wall.This loss of water in a plant cell is called plasmolysis.Answer:D. plasmolyzed
