Select the incorrect match

Options

A. Mn - Photolysis of water
B. Fe - Carbohydrate and water transiocation
C. S - Constituent of coenzyme A
D. Ca. - Synthesis of middle lamella

Answer

To determine the incorrect match among the given options related to mineral nutrition in plants, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Manganese - Photosynthesis of Water**:
- Manganese is a micronutrient that plays a crucial role in photosynthesis. It acts as a cofactor for enzymes involved in the photolysis of water, which is the process of splitting water molecules to release oxygen during photosynthesis.
- **Conclusion**: This match is correct.

2. **Iron - Carbohydrate and Water Translocation**:
- Iron is another essential micronutrient that is primarily involved in electron transport systems, particularly in cytochromes found in chloroplasts and mitochondria. It is not directly involved in carbohydrate and water translocation.
- The function of carbohydrate and water translocation is primarily associated with boron, which is a macronutrient.
- **Conclusion**: This match is incorrect.

3. **Sulfur - Constituent of Coenzyme A**:
- Sulfur is a macronutrient that is a vital component of amino acids like cysteine and is indeed a constituent of coenzyme A. It plays a role in various physiological processes, including protein synthesis.
- **Conclusion**: This match is correct.

4. **Calcium - Synthesis of Middle Lamella**:
- Calcium is important for the structural integrity of plant cells, particularly in the formation of the middle lamella, which is the layer that cements plant cells together. It also plays regulatory roles in various physiological processes.
- **Conclusion**: This match is correct.

### Final Conclusion:
The incorrect match is **Iron - Carbohydrate and Water Translocation**.
