Water is transient in plants, less than 1 percent of the water reaching the leaves is used in photosynthesis and plant growth.

Answer

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement claims that water is transient in plants and that less than 1% of the water reaching the leaves is utilized in photosynthesis and plant growth.

2. **Defining Transience of Water in Plants**: Water is considered transient in plants because it moves through the plant system but is not retained for long periods. Instead, it is primarily used for various physiological processes and then lost.

3. **Photosynthesis Process**: Photosynthesis is the process by which plants convert light energy into chemical energy, using water and carbon dioxide as raw materials. However, it is important to note that only a small fraction of the water absorbed by the roots is actually used in this process.

4. **Quantifying Water Usage**: Research indicates that less than 1% of the water that reaches the leaves is used in photosynthesis. This means that the majority of the water is not used for this purpose.

5. **Role of Transpiration**: The majority of the water absorbed by plants is lost through transpiration, which occurs through small openings on the leaves called stomata. Transpiration is the process of water vapor loss from the plant to the atmosphere.

6. **Conclusion**: Since it is true that less than 1% of the water reaching the leaves is used in photosynthesis and growth, the statement is confirmed to be true.

**Final Answer**: The statement is true.
