A plant requires nitrogen and sulphur for its

Options

A. cell walls
B. storage vacuoles
C. enzymes
D. energy stores

Answer

To answer the question regarding what a plant requires nitrogen and sulfur for, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Role of Nitrogen in Plants**:
- Nitrogen is a crucial element in the formation of amino acids, which are the building blocks of proteins. Proteins are essential for various functions in plants, including growth and development.

2. **Identify the Role of Sulfur in Plants**:
- Sulfur is also important for the synthesis of certain amino acids (like cysteine and methionine) and is a component of some coenzymes. It plays a vital role in the formation of proteins and enzymes.

3. **Analyze the Options Provided**:
- **Cell Wall**: The primary components of plant cell walls are cellulose, hemicellulose, and pectin, which do not primarily require nitrogen or sulfur.
- **Storage Vacuoles**: These are primarily involved in storing nutrients and waste products, but they do not specifically require nitrogen or sulfur for their structure.
- **Enzymes**: Enzymes are proteins that catalyze biochemical reactions. Since both nitrogen and sulfur are essential for the synthesis of proteins and enzymes, this option is highly relevant.
- **Energy Store**: Energy in plants is stored in the form of ATP, which primarily contains phosphorus, not nitrogen or sulfur.

4. **Conclusion**:
- Based on the analysis, the most appropriate answer is that a plant requires nitrogen and sulfur for the synthesis of **enzymes**.

### Final Answer:
A plant requires nitrogen and sulfur for its **enzymes**.
