Assertion : Entry of water from soil into xylem takes place through gradient of suction pressure.
Reason : Water moves from a place of higher suction pressure to a place of lower suction pressure.

Options

A. If both Assertion and Reason are true and Reason is correct explanation of Assertions.
B. If both Assertion and Reason are true but Reason is not correct explanation of Assertion.
C. If Assertion is true but Reason is false.
D. If both Assertion and Reason are false.

Answer

To solve the question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Entry of water from soil into xylem takes place through a gradient of suction pressure."
- This is correct because water moves into the xylem due to a difference in suction pressure, which is essentially the ability of the xylem to draw water in.

2. **Understanding the Reason**:
- The reason states that "Water moves from a place of higher suction pressure to a place of lower suction pressure."
- This statement is incorrect. Water actually moves from areas of lower suction pressure (where there is more water) to areas of higher suction pressure (where there is less water) in order to equalize the pressure difference.

3. **Evaluating the Options**:
- Option 1: Both assertion and reason are true, and reason is a correct explanation of assertion. (Incorrect, because the reason is false.)
- Option 2: Both assertion and reason are true, and reason is not a correct explanation of assertion. (Incorrect, because the reason is false.)
- Option 3: Assertion is true but reason is false. (Correct, since the assertion is true and the reason is false.)
- Option 4: Both assertion and reason are false. (Incorrect, because the assertion is true.)

4. **Conclusion**:
- The correct answer is that the assertion is true, but the reason is false.

### Final Answer:
- The assertion is true, and the reason is false. Therefore, the correct option is that the assertion is true but the reason is false.
