• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Assertion:

To counteract the increase in turgor pressure in plants cells, the cell wall produces an equal and opposite pressure, i.e., wall pressure.

Reason:

When plant cells undergo endosmosis, they swell but do not burst.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

Turgor pressure is the pressure which develops in the confined part of an osmotic system due to osmotic entry of water into it. It is also called hydrostatic pressure or pressure potential. The force exerted by the cell wall over the protoplast is called wall pressure. Normally wall pressure is equal and opposite to turgor pressure except when the cell becomes flaccid.
