The correct Answer is:
To solve the question regarding the modifications of a particular species of plant that produces light, non-sticky pollen in large numbers and has long, feathery stigmas, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Pollination**: - Pollination is the process of transferring pollen grains from the anther (male part) of a flower to the stigma (female part) of a flower. This is essential for fertilization and reproduction in flowering plants. 2. **Identifying the Characteristics**: - The plant in question produces **light, non-sticky pollen** in large quantities. - The stigmas of this plant are described as **long and feathery**. 3. **Analyzing the Characteristics**: - **Light, non-sticky pollen**: This characteristic suggests that the pollen is adapted for being carried by the wind. Sticky pollen would adhere to surfaces and not travel far, while light pollen can be easily dispersed over long distances. - **Large quantities of pollen**: Producing pollen in large numbers increases the chances of successful pollination, as not all pollen will reach a stigma. - **Long, feathery stigmas**: These structures can catch and hold pollen grains more effectively as they are carried by the wind, increasing the likelihood of successful fertilization. 4. **Determining the Pollination Mechanism**: - Based on the characteristics observed, it is evident that these adaptations are specifically suited for **wind pollination** (anemophily). - In wind-pollinated plants, the pollen is often lightweight and produced in large quantities to ensure that some grains reach the stigmas of other flowers. 5. **Conclusion**: - Therefore, the modifications of producing light, non-sticky pollen in large numbers and having long, feathery stigmas facilitate pollination by **wind**. ### Final Answer: These modifications facilitate pollination by **wind**.
