The correct Answer is:
To solve the question "Water is essential for growth for," we need to analyze each of the provided options based on the role of water in plant growth. ### Step-by-Step Solution: 1. **Understanding the Role of Water in Plants**: - Water is a crucial component of plant cells, making up about 90% of their body. It plays multiple roles in plant growth and development. 2. **Analyzing Option (A): Enlargement of Cells**: - Water contributes to cell enlargement by filling the vacuoles in plant cells. This turgor pressure helps cells expand, leading to overall growth. Thus, water is essential for the enlargement of cells. 3. **Analyzing Option (B): Turgidity of Cells for Extension of Growth**: - Turgidity is the state of being swollen or firm due to the high fluid content within the cells. Water maintains turgidity, which is vital for the structural integrity of plant cells and allows for growth extension. Therefore, water is essential for maintaining turgidity. 4. **Analyzing Option (C): Providing Medium for Enzymatic Activities**: - Water serves as a solvent and medium for various biochemical reactions, including enzymatic activities. It facilitates the transport of nutrients and the biochemical processes necessary for growth. Hence, water is essential for providing a medium for enzymatic activities. 5. **Analyzing Option (D): The Source of Energy**: - While water is essential for many processes in plants, it is not a source of energy. The primary source of energy for plants is sunlight, which is used in photosynthesis. Therefore, this option is incorrect. 6. **Conclusion**: - Based on the analysis, options (A), (B), and (C) are correct. The only incorrect option is (D). ### Final Answer: The correct options are (A), (B), and (C). Water is essential for growth for enlargement of cells, turgidity of cells for extension of growth, and providing a medium for enzymatic activities. ---
