Assertion : In plants water moves from higher water potential to lower water potential.
Reason : Energetically water moves form higher to lower energy.

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

**Step-by-Step Solution:**

1. **Understanding the Assertion:**
- The assertion states that "In plants, water moves from higher water potential to lower water potential." This is a true statement. Water potential is a measure of the potential energy in water, and it dictates the direction of water movement in plants.

2. **Understanding Water Potential:**
- Water potential is influenced by solute concentration and pressure. In plants, the water potential in the soil is typically higher (less negative) than that in the plant cells, which have a higher concentration of solutes. Therefore, water moves from the soil (higher water potential) into the plant roots (lower water potential) through osmosis.

3. **Understanding the Reason:**
- The reason states that "Energetically, water moves from higher to lower energy." This statement is misleading. While it is true that water moves from areas of higher potential to lower potential, the term "energy" in this context can be confusing. Water moves due to differences in water potential, not simply due to energy considerations.

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

5. **Conclusion:**
- The correct answer is Option 3: Assertion is true, and reason is false.
