Assertion : Guttation takes place through hydathodes.
Reason : Each stoma is made up of two kidney shaped guard cells in dicots.

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 analyze the assertion and reason provided in the question, we can break it down step by step:

### Step 1: Understanding Guttation
- **Definition**: Guttation is the process by which plants lose water in the form of liquid droplets. This typically occurs at the edges or tips of leaves.
- **Mechanism**: Guttation occurs through specialized structures called hydathodes, which are located at the leaf margins.

### Step 2: Evaluating the Assertion
- **Assertion**: "Guttation takes place through hydathodes."
- **Analysis**: This statement is correct. Guttation indeed occurs through hydathodes, which release water droplets when the plant has excess moisture.

### Step 3: Understanding Stomata
- **Definition**: Stomata are small openings on the surfaces of leaves that facilitate gas exchange and transpiration.
- **Structure**: Each stoma is surrounded by two kidney-shaped guard cells that control its opening and closing.

### Step 4: Evaluating the Reason
- **Reason**: "Each stoma is made up of two kidney-shaped guard cells in dicots."
- **Analysis**: This statement is also correct. Stomata in dicots are indeed composed of two guard cells that regulate the stomatal pore.

### Step 5: Relationship Between Assertion and Reason
- **Comparison**: While both the assertion and reason are correct, they refer to different processes. Guttation (involving hydathodes) and transpiration (involving stomata) are distinct processes.
- **Conclusion**: The reason does not explain the assertion, as they pertain to different mechanisms of water loss in plants.

### Final Conclusion
- Both the assertion and reason are correct, but the reason does not provide a correct explanation for the assertion. Therefore, the correct option is that both statements are true, but the reason is not the correct explanation for the assertion.
