The correct Answer is:
To determine which statements about Cycas are correct, let's analyze the options step by step: ### Step 1: Analyze the first statement **Statement:** Cycas has characteristics of branched stems and pinnate leaves. **Analysis:** - Cycas can have either branched or unbranched stems. - It is true that Cycas has pinnate leaves, but the statement about branched stems is not universally applicable. **Conclusion:** This statement is **incorrect**. ### Step 2: Analyze the second statement **Statement:** Cycas is a dioecious plant. **Analysis:** - Dioecious means that male and female reproductive organs are found on separate plants. - In Cycas, male cones and female structures (megasporophylls) are indeed found on different plants. **Conclusion:** This statement is **correct**. ### Step 3: Analyze the third statement **Statement:** Mycorrhizal associations are commonly found in the roots of Cycas. **Analysis:** - Cycas roots are known for having coralloid roots, which form a symbiotic relationship with cyanobacteria, not mycorrhizal fungi. - Therefore, the statement about mycorrhizal associations is incorrect. **Conclusion:** This statement is **incorrect**. ### Final Conclusion The only correct statement about Cycas is that it is a dioecious plant. Therefore, the correct answer is **option B**. ---
