Question

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Select the correct option.
Assertion (A): Plant cell does not burst when placed in hypotonic condition.
Reason (R): Cell wall withstands the internal pressure of the swollen cell.

• A. (A) is correct and (R) is incorrect
• B. Both (A) and (R) are correct
• C. Both (A) and (R) are incorrect
• D. (A) is incorrect and (R) is correct

Answer 1

The correct option is B Both (A) and (R) are correct

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Cell wall provides mechanical support to the plant cell. When a plant cell is kept in a hypotonic solution, water enters the cell but it does not burst because of the pressure applied by the cell wall. Since it is rigid, it does not allow the cell to expand to an extent that it would burst.
