The correct Answer is:
To analyze the role of water in plant life based on the provided statements, we will evaluate each statement for its accuracy and relevance. ### Step-by-Step Solution: 1. **Statement (a)**: "It provides the medium in which most substances are dissolved." - **Analysis**: This statement is true. Water acts as a solvent in plants, allowing nutrients and minerals to dissolve and be transported throughout the plant. 2. **Statement (b)**: "Dry matter in most herbs is about 10 to 15 percent of its fresh weight." - **Analysis**: This statement is also true. In most herbs, the majority of their fresh weight (approximately 85-90%) is water, while the dry matter constitutes only about 10-15%. 3. **Statement (c)**: "Distribution of water within a plant varies." - **Analysis**: This statement is correct. Water distribution varies in different parts of the plant, with roots generally having more water than woody parts like stems. 4. **Statement (d)**: "Woody parts have relatively very little water." - **Analysis**: This statement is true. Woody parts of the plant, such as stems and branches, contain less water compared to other parts like leaves and roots. 5. **Statement (e)**: "A dry seed has no water." - **Analysis**: This statement is incorrect. While a dry seed has very low moisture content, it does not contain "no water" at all. There is usually a small amount of water present, which is essential for the seed's ability to germinate. ### Conclusion: Based on the analysis: - Statements (a), (b), (c), and (d) are correct. - Statement (e) is incorrect. Thus, the correct answer is that statements A, B, C, and D are correct.
