[R]: Turgor pressure checks the excessive entry of water into cells.

Options

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

Answer

B

Explanation

When a plant cell placed in hypertonic solution the water moves out of the cell, as a result, the cell get plasmolyzed and thus results in loss of turgidity.
The actual pressure exerted by the protoplasm against the cell wall is called turgor pressure. The cell wall is rigid and elastic therefore it exerts an equal and opposite pressure against the expanding protoplasm.
