Question

Assertion : A plant cell bursts if placed in water
Reason : High turgor pressure causes bursting of plant cells

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (D)

Plant cells have cell wall to counteract turgor pressure $(T.P)$ by exerting exactly equal and opposite wall pressure. Wall pressure stops entry of water into plant cells beyond a certain limit thus prevents their bursting
