The correct Answer is:
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 "Most orchid seedlings cannot develop well in the absence of fungal mycelium." This is true. Orchid seedlings are known to have a symbiotic relationship with fungi, which is crucial for their development. The fungi provide essential nutrients that the orchid seeds cannot absorb on their own. 2. **Understanding the Reason**: The reason given is that "Fungal mycelium increases efficiency of absorption only." This statement is misleading. While fungal mycelium does play a role in nutrient absorption, it does not solely increase absorption efficiency. Instead, it also aids in the storage of nutrients and converts them into forms that the orchids can utilize. 3. **Evaluating the Relationship**: The assertion is correct, as it accurately describes the dependency of orchid seedlings on fungal mycelium for growth. However, the reason is incorrect because it oversimplifies the role of fungal mycelium, failing to acknowledge its function in nutrient storage and conversion. 4. **Conclusion**: Based on the analysis, the assertion is true, but the reason is false. Therefore, the correct answer is that the assertion is true and the reason is false. ### Final Answer: Assertion is true, but the reason is false. ---
