Question

Given below are two statements: Statement I: Cell wall is freely permeable.
Statement II: Plasma membrane is selectively permeable.
Choose the correct answer from the options given below with reference to the structure of root hair:

• A. Statement I is incorrect but Statement II is correct
• B. Both Statement I and Statement II are correct
• C. Both Statement I and Statement II are incorrect
• D. Statement I is correct but Statement II is incorrect

Hint:

The cell wall facilitates unrestricted movement, while the plasma membrane controls selective permeability to maintain homeostasis in the cell.

Answer 1

The Correct Option is B

Statement I: Cell wall is freely permeable.
The cell wall in plants is freely permeable to water and solutes. This allows the movement of substances through the apoplast pathway, ensuring easy transport across the cell wall. Hence, Statement I is correct. Statement II: Plasma membrane is selectively permeable.
The plasma membrane regulates the entry and exit of substances into the cell. It is selectively permeable, allowing only specific molecules (e.g., ions, nutrients) to pass through, while restricting others. Hence, Statement II is correct. Conclusion:
Since both statements are correct, the correct answer is: \[ \mathbf{(B) \ Both \ Statement \ I \ and \ Statement \ II \ are \ correct.} \]
