Answer 1

Answer:

Plasmolysis occurs when a plant cell is inmersed in a 3X salt solution.

Explanation:

Plasmolysis is a phenomenon only observed in plant cells, and consists of cell dehydration accompanied by separation of the membrane and cell wall when the cell is exposed in a hypertonic environment.

When a plant cell is in a hypertonic solution —such as 3X salt solution— the permeability of its membrane allows water to escape, so the cell dehydrates and reduces its size. The cell wall is rigid and maintains its shape, but the cell membrane separates from it, which is known as plamolysis.

The other alternative answer combinations are not correct because:

• Plamolysis does not occur in animal cells.
• Pure water does not produce plasmolysis.
