The plants convert light into chemical energy with a photosynthetic efficiency of

Options

A. `3-6 %`
B. `6-20 %`
C. `20-35 %`
D. `35-41 %`

Explanation

To solve the question regarding the photosynthetic efficiency of plants, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Photosynthesis**:
- Photosynthesis is the process by which plants convert light energy from the sun into chemical energy in the form of glucose (sugar). This process occurs mainly in the chloroplasts of plant cells.

2. **Defining Photosynthetic Efficiency**:
- Photosynthetic efficiency refers to the percentage of light energy that is converted into chemical energy during photosynthesis. It is a measure of how effectively plants can utilize sunlight.

3. **Identifying the Range of Efficiency**:
- Research indicates that the photosynthetic efficiency of plants typically ranges from about 3% to 6%. This means that only a small fraction of the sunlight that hits the leaves is converted into usable energy.

4. **Evaluating the Options**:
- Given the options:
- Option 1: 3-6% (Correct)
- Option 2: 6-20% (Incorrect)
- Option 3: 20-35% (Incorrect)
- Option 4: 35-41% (Incorrect)
- The only option that accurately reflects the photosynthetic efficiency of plants is Option 1 (3-6%).

5. **Conclusion**:
- Therefore, the correct answer to the question about the photosynthetic efficiency of plants is **3-6%**.
