Select the correctly matched pair

Options

A. Zinc-Helps to maintain the ribosome structure
B. Magnesium-needed during the formation of mitotic spindle
C. Calcium -Plays a role in the opening and closing of stomata
D. Manganese-needed in the splitting of water to liberate oxygen during photosynthesis

Answer

To solve the question of selecting the correctly matched pair, we will follow these steps:

### Step 1: Understand the Question
The question asks us to identify a correctly matched pair from the given options. Each option likely consists of a mineral and its associated function in plant nutrition.

### Step 2: Analyze the Options
We need to carefully examine each option provided in the question. Since the specific options are not listed here, we will focus on understanding the general roles of some common minerals in plants.

### Step 3: Identify Key Functions of Minerals
- **Manganese (Mn)**: It is essential for the splitting of water during photosynthesis, which is crucial for oxygen release.
- **Iron (Fe)**: Important for chlorophyll synthesis and electron transport in photosynthesis.
- **Zinc (Zn)**: Plays a role in enzyme function and protein synthesis.
- **Magnesium (Mg)**: Central atom in chlorophyll and important for photosynthesis.

### Step 4: Match Each Mineral with Its Function
Now, we will match the minerals with their respective functions:
- Manganese: Splitting of water in photosynthesis (correct match)
- Iron: Chlorophyll synthesis (correct match)
- Zinc: Enzyme function (correct match)
- Magnesium: Central in chlorophyll (correct match)

### Step 5: Select the Correctly Matched Pair
From the analysis, we find that manganese is correctly matched with its function of splitting water to liberate oxygen during photosynthesis. Therefore, the correct answer is the option that states "Manganese needed in the splitting of water to liberate oxygen during photosynthesis."

### Conclusion
The correctly matched pair is manganese with its function in photosynthesis.
