Assertion: The resin duct in coniferales is schizogenous in origin.
Reason: Resin duct helps to retain water as well as seals the injured areas of plants.

Options

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

Answer

To solve the question regarding the assertion and reason about resin ducts in Coniferales, we will break it down step by step.

### Step 1: Understand the Assertion
The assertion states that "The resin duct in Coniferales is schizogenous in origin."
- **Explanation**: Schizogenous refers to a type of tissue development where cells separate to form a cavity. In Coniferales, resin ducts are formed by the splitting of cells, which aligns with the definition of schizogenous origin.

### Step 2: Understand the Reason
The reason states that "Resin duct helps to retain water as well as seals the injured areas of plants."
- **Explanation**: Resin ducts do indeed play a role in water retention and sealing off injured areas. They secrete resin, which can help prevent water loss and seal wounds, thus protecting the plant from pathogens and further injury.

### Step 3: Analyze the Relationship Between Assertion and Reason
- Both the assertion and reason are true statements. However, we need to determine if the reason correctly explains the assertion.
- The assertion describes the origin of resin ducts, while the reason describes their function. Therefore, while both statements are true, the reason does not provide a correct explanation for the assertion.

### Step 4: Conclusion
Based on the analysis:
- The assertion is true.
- The reason is true but does not explain the assertion.
- Thus, the correct answer is that both the assertion and reason are true, but the reason is not the correct explanation of the assertion.

### Final Answer
The correct answer is **Option B**: Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
