The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understand the Assertion**: - The assertion states that "Most of the orchids are dependent on fungi in the seedling stage." - This means that during their early growth phase, orchids rely on fungi for their development and nutrition. 2. **Understand the Reason**: - The reason states that "The fungal mycelium penetrates the cortical cells of orchid roots." - This indicates that the fungi invade the root cells of orchids, which is a crucial part of their relationship. 3. **Evaluate the Truth of Each Statement**: - **Assertion**: It is true that most orchids are dependent on fungi during their seedling stage. Orchids lack the ability to store nutrients effectively, so they rely on fungi for nutrition. - **Reason**: It is also true that the fungal mycelium penetrates the cortical cells of the orchid roots. This penetration allows the fungi to assist the orchids in nutrient absorption. 4. **Determine the Relationship Between Assertion and Reason**: - While both statements are true, the reason does not directly explain why orchids are dependent on fungi. The assertion speaks to the dependency, while the reason describes a mechanism of interaction but does not clarify the dependency itself. 5. **Conclusion**: - Both the assertion and reason are true, but the reason is not the correct explanation of the assertion. Therefore, the final answer is that both statements are true, but the reason does not explain the assertion. ### Final Answer: Both the assertion and reason are true, but the reason is not the correct explanation of the assertion. ---
