Question

Arrange the following into its correct order of occurence.

i. plasmolysis
ii. movement of water out of cytoplasm
iii. shrinkage of protoplasm away from the cell wall
iv. movement of water out of vacuole
v. cell in hypertonic solution

• A. v, ii, iv, iii, i
• B. v, iv, ii, iii, i
• C. v, iv, iii, ii, i
• D. i, ii, iii, iv, v

Answer 1

The correct option is A v, ii, iv, iii, i

Plasmolysis occurs when water moves out of the cell and the protoplasm of the plant shrinks away from its cell wall. This occurs when the cell is placed in hypertonic solution (solution having more concentration of solute than cytoplasm of the cell). Water is first lost from the cytoplasm and then from the vacuole. This causes the protoplast to shrink away from the walls, resulting in plasmolysis of the cell.
