Question

Plasmolysis in a plant cell is defined as

• A. Shrinkage of cytoplasm in hypertonic medium
• B. Shrinkage of nucleoplasm
• C. Break down (lysis ) of plasma membrane in hypotonic medium
• D. None of the above

Answer 1

The correct option is A Shrinkage of cytoplasm in hypertonic medium

Living plant cell loses water through osmosis resulting in shrinkage or contraction of the contents of the cell away from the cell wall. This phenomenon is known as plasmolysis. When plant cell has more water content than in the surrounding plant cell tend to transfer water to its surroundings which results in shrinkage of the cell through plasmolysis.
