Solution
The correct option is A Hypertonic solution
When plant cells are kept in a hypertonic solution (i.e., a solution more concentrated than the plant cell sap) they lose water due to the process of exosmosis. This causes plasmolysis, a process in which protoplasm leaves cell wall and lies shrunk inside the cell. When the cell is kept in hypotonic solution (i.e., a solution far less concentrated than the plant cell sap), it gains water due to the process of endosmosis. The cell now swells and is called as deplasmolyzed cell. If plant cells are kept in isotonic solution, no changes take place. Thus, the correct answer is option B.
