How much of water reaching the leaves is used in photosynthesis and plant growth

Options

A. Less than 5 percent
B. Less than 1 percent
C. Less than 10 percent
D. Less than 4 percent

Answer

**Step-by-Step Solution:**

1. **Understanding Water Movement in Plants:**
- Water is transported through the plant via the xylem, which is the vascular tissue responsible for the conduction of water and dissolved nutrients from the roots to the leaves.

2. **Role of Water in Photosynthesis:**
- Water is a crucial component of the photosynthesis process. It is used as a raw material in the chemical reaction that converts carbon dioxide and sunlight into glucose and oxygen.

3. **Quantifying Water Usage:**
- Research indicates that a very small percentage of the water that reaches the leaves is actually used for photosynthesis.

4. **Percentage of Water Used:**
- Studies show that less than 1% of the water that is absorbed by the plant and transported to the leaves is utilized in the process of photosynthesis and plant growth.

5. **Conclusion:**
- Therefore, the answer to the question is that less than 1% of the water reaching the leaves is used in photosynthesis and plant growth.

**Final Answer:**
Less than 1% of the water reaching the leaves is used in photosynthesis and plant growth.
