Question:medium

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:

Show Hint

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

  • Statement I is incorrect but Statement II is correct
  • Both Statement I and Statement II are correct
  • Both Statement I and Statement II are incorrect
  • Statement I is correct but Statement II is incorrect
Hide Solution

The Correct Option is B

Solution and Explanation

Statement I: Cell wall is freely permeable.
In plants, the cell wall permits unrestricted passage of water and solutes. This facilitates movement via the apoplast pathway, ensuring efficient transport across the cell wall. Therefore, Statement I is correct.Statement II: Plasma membrane is selectively permeable.
The plasma membrane controls the passage of substances into and out of the cell. It exhibits selective permeability, permitting only specific molecules (e.g., ions, nutrients) to cross while impeding others. Consequently, Statement II is correct.Conclusion:
As both statements are accurate, the correct option is:\[\mathbf{(B) \ Both \ Statement \ I \ and \ Statement \ II \ are \ correct.}\]
