解释
Plasmolysis is a process that occurs when a plant cell loses water and shrinks due to being in a hypertonic solution, which is a solution with a high concentration of solutes like salt. The cell membrane detaches from the cell wall, and the protoplasm shrinks away.
The cytoplasm and plasma membrane of a plant cell shrink during plasmolysis, not the stomata. Option A
