The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Wind Pollination:** - Wind-pollinated flowers are adapted to utilize wind as a means of transferring pollen from the male parts (anthers) to the female parts (stigmas) of flowers. 2. **Characteristics of Wind Pollinated Flowers:** - These flowers are generally small and inconspicuous. - They lack bright colors and petals, as these features are not necessary for attracting pollinators. - They do not produce nectar, which is typically used to attract insects. 3. **Stigma Characteristics:** - The stigma of wind-pollinated flowers is often feathery or branched. This structure increases the surface area and helps in effectively trapping pollen grains carried by the wind. - The stigma is usually exerted, meaning it is positioned outside the flower, allowing it to catch pollen more efficiently. 4. **Exerted vs. Inserted Stigma:** - An exerted stigma is one that extends out of the flower, making it more accessible to airborne pollen. - An inserted stigma is positioned inside the flower, which is less effective for wind pollination. 5. **Conclusion:** - Based on the characteristics discussed, the correct answer is that a characteristic of wind-pollinated flowers is a "feathery exerted stigma." **Final Answer:** The characteristic of wind-pollinated flowers is a feathery exerted stigma. ---
