The correct Answer is:
To answer the question about the direction of the micropyle in an anatropous ovule, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Anatropous Ovule**: - An anatropous ovule is characterized by its complete inversion, meaning it has rotated 180 degrees from its original position. 2. **Identifying the Micropyle**: - The micropyle is a small opening in the ovule that allows the pollen tube to enter for fertilization. In most ovules, the micropyle is typically located at the top. 3. **Effect of Inversion**: - In the case of an anatropous ovule, due to the 180-degree rotation, the position of the micropyle changes. Instead of being at the top, it moves to the bottom of the ovule. 4. **Location of Micropyle**: - In an anatropous ovule, the micropyle is positioned at the downward end, close to the hilum (the point of attachment of the ovule to the ovary). 5. **Conclusion**: - Therefore, in an anatropous ovule, the direction of the micropyle is downward. ### Final Answer: The direction of the micropyle in an anatropous ovule is downward. ---
