What will happen to the onion skin cells after distilled water is added?

Question

the cells are suppose to shrink once salt solution is added, but after adding distilled water will it bloat up or just go back to its original size before the salt solution was added?

Answer 1

when salt water is added the cells shrink this is called plasmolosis. this is because the water in the cell is moving out of the cell from a high water concentration(inside the cell) to a low water concentration (outside the cell). when distilled water is added to the cell it will bloat up as the water moves from outside the cell to inside the cell. it will not return to its normal size as the volume of water entering the cell cannot be controlled.
