Type: MCQ • Marks: 1
Plant cell walls allow the cells to withstand very dilute (hypotonic) external media without bursting because:
Options
A. A) The cell wall permits immediate plasmolysis to release excess pressure.
B. B) The wall exerts an equal pressure against the swollen cell.
C. C) The cell wall expands infinitely to accommodate incoming water
D. D) The cell wall dissolves to allow fast exit of internal water.
Explanation
The cell swells, building up pressure against the cell wall. The wall exerts an equal pressure against the swollen cell, allowing plant cells to withstand greater changes than animal cells.
