Very strong light has a direct inhibiting effect on photosynthesis, which is known as

Options

A. Solarisation
B. Etiolation
C. Chlorosis
D. Defoliation

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes the direct inhibiting effect of very strong light on photosynthesis.

2. **Identifying the Options**: The options provided are:
- A) Solarization
- B) Etiolation
- C) Chlorosis
- D) Defoliation

3. **Analyzing Each Option**:
- **Solarization**: This term refers to the process where excessive light intensity leads to the photo-oxidation of photosynthetic cells, ultimately inhibiting photosynthesis.
- **Etiolation**: This refers to the growth of plants in the absence of light, which is not related to the effect of strong light.
- **Chlorosis**: This term describes the yellowing of leaf tissue, which is not directly related to the effects of strong light on photosynthesis.
- **Defoliation**: This means the loss of leaves from a plant, which again does not specifically refer to the impact of strong light.

4. **Selecting the Correct Answer**: Based on the analysis, the correct term that describes the inhibiting effect of very strong light on photosynthesis is **Solarization**.

5. **Conclusion**: Therefore, the answer to the question is **A) Solarization**.
