Experiment: Different concentrations of salt solution were added to onion cells under a microscope. Their vacuoles and membranes were observed.Observation: Higher salt concentrations caused vacuole shrinkage and membrane pulling away from the wall.Question: What is the correct interpretation?
Correct answer: D. Plasmolysis occurs due to water loss in hypertonic solutions.
- A. Salt enters the vacuole and bursts the cell.
- B. Water floods into onion cells in salt solution.
- C. Salt thickens the cell wall.
- D. Plasmolysis occurs due to water loss in hypertonic solutions.
Explanation
In this experiment, the higher salt concentrations led to vacuole shrinkage and membranes pulling away from the cell wall, indicating plasmolysis where water leaves the cell in a hypertonic solution, causing it to shrink. The correct interpretation is that plasmolysis occurs due to water loss in hypertonic solutions. The other options are incorrect because they do not align with the observed results of the experiment.
