The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Pollination**: - Pollination is the process of transferring pollen grains from the male part of a flower (anther) to the female part (stigma) to facilitate fertilization. 2. **Types of Pollination**: - There are various types of pollination, including: - **Anemophily**: Pollination by wind. - **Hydrophily**: Pollination by water. 3. **Characteristics of Wind and Water Pollinated Flowers**: - Flowers that are pollinated by wind (anemophilous) and water (hydrophilous) tend to be less colorful and do not produce nectar. This is because: - They do not rely on insects for pollination. - Their pollen is dispersed through air or water, making bright colors and nectar unnecessary. 4. **Assertion Analysis**: - The assertion states that both wind and water pollinated flowers are not very colorful and do not produce nectar. This is true as explained above. 5. **Reason Analysis**: - The reason states that color and nectar act as insect attractants. This is also true, as colorful flowers and nectar are adaptations to attract pollinators, primarily insects. 6. **Relationship Between Assertion and Reason**: - The assertion and reason are both true, and the reason provides a correct explanation for the assertion. Wind and water pollinated flowers do not need to attract insects, hence they lack color and nectar. 7. **Conclusion**: - The correct answer is that both the assertion and reason are true, and the reason is the correct explanation of the assertion. ### Final Answer: - **Option A**: Both the assertion and reason are true, and the reason is the correct explanation of the assertion. ---
