The correct Answer is:
To analyze the given statements, we will evaluate each one step by step. ### Step 1: Evaluate Statement A **Statement A:** Male gametophyte in gymnosperms is highly reduced. - In gymnosperms, the male gametophyte is indeed highly reduced. - The male gametophyte develops within the pollen grain, which is a small structure that contains the male gametes (sperm cells). - This reduction is a characteristic feature of gymnosperms, as they have evolved to have a more compact and efficient reproductive structure. **Conclusion for Statement A:** This statement is correct. ### Step 2: Evaluate Statement B **Statement B:** Megasporophylls are compactly arranged in Cycas. - Cycas is a genus of gymnosperms, and it is important to understand the arrangement of megasporophylls in this plant. - In Cycas, the megasporophylls (which bear the ovules) are actually arranged loosely, not compactly. - This means that the statement claiming that megasporophylls are compactly arranged is incorrect. **Conclusion for Statement B:** This statement is incorrect. ### Final Conclusion - Statement A is correct. - Statement B is incorrect. Therefore, the answer to the question is that Statement B is the incorrect statement. ---
