Where is manganese required in the body of plants ?

Explanation

**Step-by-Step Solution:**

1. **Identify the Element**: Manganese is a trace mineral denoted by the symbol Mn. It is essential for plant growth and development.

2. **Role in Photosynthesis**: Manganese plays a crucial role in the process of photosynthesis. Specifically, it is involved in the splitting of water molecules (H2O) during the light-dependent reactions of photosynthesis.

3. **Mechanism of Action**: During photosynthesis, manganese acts as a cofactor for the enzyme that facilitates the photolysis of water. This process is vital as it produces oxygen and provides electrons needed for the conversion of light energy into chemical energy.
