Manganese:

Options

A. It plays major role in splitting of water.
B. required for the synthesis of auxin
C. essential for formation of chlorophyll
D. helps in maintaining turgidity of the cell

Answer

**Step-by-Step Solution:**

1. **Understanding the Role of Manganese:**
- Manganese is an essential micronutrient for plants. It plays a critical role in various physiological processes, particularly in photosynthesis.

2. **Manganese and Water Splitting:**
- One of the key functions of manganese is its involvement in the photolysis of water during photosynthesis. This process is crucial for the release of oxygen. Manganese acts as a cofactor in the oxygen-evolving complex of photosystem II.

3. **Evaluating the Options:**
- Let's analyze the provided options:
- **Option 1:** Manganese plays a major role in splitting of water. (True)
- **Option 2:** Required for the synthesis of auxin. (False, auxins are primarily synthesized from tryptophan and not directly dependent on manganese)
- **Option 3:** Essential for the formation of chlorophyll. (False, magnesium is essential for chlorophyll formation)
- **Option 4:** Helps in maintaining the turgidity of the cells. (False, this is primarily the role of potassium)

4. **Conclusion:**
- Based on the analysis, the correct statement regarding manganese is that it plays a major role in the splitting of water during photosynthesis.

**Final Answer:**
- Manganese plays a major role in the splitting of water during photosynthesis.
