The correct Answer is:
To solve the question regarding hydrophily and the given statements, we will analyze each statement one by one to determine which ones are correct. ### Step-by-Step Solution: 1. **Understanding Hydrophily**: - Hydrophily is a type of pollination that occurs in water. It involves the transfer of pollen grains through water currents. This is relatively rare among flowering plants, which typically rely on biotic agents like insects or birds for pollination. 2. **Analyzing Statement (i)**: - **Statement**: "It is quite rare in flowering plants." - **Analysis**: This statement is true. Hydrophily is indeed rare in flowering plants compared to other forms of pollination like entomophily (pollination by insects) or ornithophily (pollination by birds). 3. **Analyzing Statement (ii)**: - **Statement**: "Pollen grains are protected by mucilaginous covering." - **Analysis**: This statement is also true. Pollen grains that are involved in hydrophily are often covered with a mucilaginous layer to protect them while they are transported through water. 4. **Analyzing Statement (iii)**: - **Statement**: "In some plants, pollens are released inside the water." - **Analysis**: This statement is true as well. For example, in the aquatic plant Valisneria, pollen grains are released into the water, where they can be carried to other plants. 5. **Analyzing Statement (iv)**: - **Statement**: "Flowers are very colorful but without nectar." - **Analysis**: This statement is false. Typically, colorful flowers are adapted for pollination by biotic agents and often produce nectar to attract these agents. In hydrophily, flowers do not need to be colorful or produce nectar since they rely on water for pollination. ### Conclusion: Based on the analysis: - Statements (i), (ii), and (iii) are true. - Statement (iv) is false. Thus, the correct choice regarding hydrophily is that statements (i), (ii), and (iii) are correct. ### Final Answer: The right choice is that statements (i), (ii), and (iii) are correct. ---
