Answer:
contraction of the protoplast of a plant cell as a result of loss of water from the cell.
Plasmolysis occurs, when a cell is kept in hypertonic solution (solution with higher solute concentration). During this process, cell loses water and cell membrane detaches from cell wall. Plant cell shows plasmolysis but animal cell does not show plasmolysis, because, animal cells lack cell wall.
