WBCS.LIVE practice question

A healthy plant cell visibly shrinks and pulls away from its cell wall (plasmolysis) when it is placed directly into which type of solution?

Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. Isotonic solution
  2. Hypotonic solution
  3. Amphoteric solution
  4. Hypertonic solution

Correct answer and explanation

Correct answer: Hypertonic solution

Explanation: āœ… Correct Answer: D) Hypertonic solution šŸ“š Explanation: A hypertonic solution possesses a significantly higher concentration of solutes compared to the inside of the cell. Through the biological process of osmosis, water rapidly moves from an area of higher water potential (inside the cell) to lower water potential (outside). This massive water loss heavily forces the cell membrane to shrink away from the rigid plant cell wall, a process called plasmolysis.
