Land plants utilize for photosynthesis

Options

A. 1% of water absorbed
B. 10% of water absorbed
C. 25% of water absorbed
D. 20% of water absorbed

Answer

### Step-by-Step Solution:

1. **Understanding Photosynthesis**:
- Photosynthesis is the process by which land plants convert light energy into chemical energy to produce food. This process primarily occurs in the chloroplasts of plant cells.

2. **Key Components of Photosynthesis**:
- The main components required for photosynthesis are sunlight, carbon dioxide (CO2), and water (H2O).
- Sunlight provides the energy needed for the process, while CO2 is absorbed from the atmosphere, and water is absorbed from the soil.

3. **Role of Water in Photosynthesis**:
- Water plays a crucial role in the light-dependent reactions of photosynthesis. It is split into oxygen, protons, and electrons in a process known as photolysis, which occurs in the presence of light.

4. **Water Absorption in Land Plants**:
- Land plants absorb water from the soil through their roots. The question specifically asks about the percentage of water utilized for photosynthesis.

5. **Analyzing the Options**:
- The provided options are 1%, 10%, 25%, and 20%.
- Based on the understanding of photosynthesis, it is established that land plants utilize a small percentage of the water they absorb for the photosynthesis process.

6. **Conclusion**:
- The correct answer to the question "Land plants utilize for photosynthesis" is **1%** of the water absorbed.

### Final Answer:
- **1% of water absorption is utilized by land plants for photosynthesis.**
