Photosynthetic process utilitzes _______ of water absorbed by a plant.

Options

A. 0.1
B. 0.15
C. Less than 1%
D. 0.05

Answer

**Step-by-Step Solution:**

1. **Understanding Water Absorption in Plants**: Plants absorb water primarily through their roots. This water is essential for various physiological processes, including photosynthesis.

2. **Identifying the Processes Involving Water**: There are two main processes that involve the water absorbed by plants:
- **Photosynthesis**: This is the process by which plants convert light energy into chemical energy using water and carbon dioxide.
- **Transpiration**: This is the process of water loss from the plant, mainly through small openings called stomata located on the leaves.

3. **Quantifying Water Utilization**: It is important to note that a significant portion of the water absorbed by plants is not used for photosynthesis. In fact, studies show that:
- More than 98% of the water absorbed by plants is lost through transpiration.
- Less than 2% of the absorbed water is utilized in the photosynthetic process.

4. **Conclusion**: Given the options, the most accurate answer to the question "Photosynthetic process utilizes _______ of water absorbed by a plant" is "less than 1%". This aligns with the understanding that only a small fraction of the water absorbed is used in photosynthesis.

**Final Answer**: Photosynthetic process utilizes **less than 1%** of water absorbed by a plant.
