Question

______ is the phenomenon of contraction of the cytoplasm from the cell wall.

Answer 1

Plasmolysis is the phenomenon of contraction of the cytoplasm from the cell wall.

Explanation:

Plasmolysis occurs when a living plant cell is placed in a hypertonic solution, causing water to leave the cell via exosmosis. As the vacuole loses water, the overall volume of the protoplasm shrinks, pulling the plasma membrane and cytoplasm away from the rigid cell wall. This results in a clear, visible gap between the collapsed cell contents and the cell wall under a microscope.
