Assertion: Plants obtain molybdenum in the form of molybdate ions `(MoO_(4)^(2+))`
Reason: Molybdenum is a component of pollen germination, cell elongation and cell differentiation.

Options

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

Explanation

To analyze the assertion and reason provided in the question, we can break down the information step by step.

### Step 1: Understanding the Assertion
The assertion states that "Plants obtain molybdenum in the form of molybdate ions `(MoO_(4)^(2-))`."
- Molybdenum is indeed taken up by plants primarily as molybdate ions, which is a correct statement.

### Step 2: Understanding the Reason
The reason states that "Molybdenum is a component of pollen germination, cell elongation, and cell differentiation."
- While molybdenum is important for certain enzymatic functions in plants, particularly in nitrogen fixation (as part of the nitrogenase enzyme), it is not specifically known as a key component in pollen germination. Instead, boron is the element more closely associated with pollen germination.

### Step 3: Evaluating the Truth of Both Statements
- The assertion is true because plants do take up molybdenum as molybdate ions.
- The reason is false because molybdenum is not primarily responsible for pollen germination; boron plays a more significant role in that process.

### Step 4: Conclusion
Based on the evaluation:
- The assertion is true.
- The reason is false.

Thus, the correct option would be that the assertion is true, but the reason is false.

### Final Answer:
- Assertion: True
- Reason: False
