The correct Answer is:
To solve the question regarding which option is incorrect with respect to anemophily, we can follow these steps: ### Step 1: Understand Anemophily Anemophily is a type of pollination that occurs via wind. It is common in certain plants, particularly grasses and some trees. **Hint:** Remember that anemophily relies on wind as the primary pollinating agent. ### Step 2: Identify Characteristics of Anemophily Plants that undergo anemophily have specific adaptations: - The stamens are well exposed to release pollen grains into the air. - Pollen grains are typically light to be carried by the wind. - The stigma is often feathery and sticky to effectively capture the pollen. **Hint:** Think about the adaptations that help pollen grains travel through the air and how they interact with the stigma. ### Step 3: Analyze the Options 1. **Stamens are well exposed** - This is true for anemophily. 2. **Pollen grains are light and sticky** - This is incorrect. While pollen grains are light, they are generally non-sticky to avoid sticking to surfaces other than the stigma. 3. **Feathery stigma** - This is true as it helps in capturing pollen. 4. **Flowers are colorless and nectarless** - This is also true, as these flowers do not need to attract biotic pollinators. **Hint:** Look for the statement that contradicts the known characteristics of anemophily. ### Step 4: Identify the Incorrect Option From the analysis, the incorrect statement is the one that claims pollen grains are sticky. In reality, they are non-sticky to ensure they can travel freely through the air and land on the stigma. **Hint:** Focus on the properties of pollen grains in anemophily to determine which statement is false. ### Conclusion The incorrect option with respect to anemophily is the statement that says "pollen grains are light and sticky." **Final Answer:** Option 2 is incorrect.
