Question

Which of the following occupies the space between the cell wall and the shrunken protoplast in a plasmolysed cell?

Answer 1

Answer:

If a plant cell is kept in hypertonic solution, water comes out from the cell sap due to exosmosis. Water loss from the cell sap results in contraction of protoplast, which is referred to as plasmolysis. The cell is surrounded by the hypertonic solution, and the cell wall allows entry of most of the solutions. The hypertonic solution enters the cell wall freely but is not allowed to cross the cell membrane.

Thus, the space between the cell wall and condensed protoplast is filled with hypertonic solution in a plasmolyzed cell.
