Deficiency of which group of elements can cause inhibition of cell division in plants ?

Options

A. N, K, S
B. Mg, Cu, P
C. Ca, Mg, Cu
D. N, K, Ca

Answer

To answer the question regarding which group of elements can cause inhibition of cell division in plants, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Importance of Cell Division in Plants**:
- Cell division is a crucial process in the growth and development of plants. It allows for the formation of new cells, which is essential for root and shoot development, as well as overall plant growth.

2. **Identify Essential Elements for Plant Growth**:
- Plants require 17 essential elements for their growth, which are categorized into macronutrients and micronutrients. Macronutrients are needed in larger quantities, while micronutrients are needed in smaller amounts.

3. **Recognize the Role of Macronutrients**:
- Among the macronutrients, nitrogen, potassium, and sulfur are vital for various physiological processes, including cell division. These elements contribute to the synthesis of nucleic acids and proteins, which are essential for cell division.

4. **Consider Micronutrients**:
- Molybdenum is a micronutrient that also plays a role in cell division. However, since the question focuses on groups of elements and does not include molybdenum, we will concentrate on the macronutrients.

5. **Analyze the Options Given**:
- The options provided include various combinations of elements. The first option lists nitrogen, potassium, and sulfur, which are known to inhibit cell division when deficient.

6. **Conclude the Answer**:
- Based on the analysis, the deficiency of nitrogen, potassium, and sulfur can lead to the inhibition of cell division in plants. Therefore, the correct answer is the first option: **Nitrogen, Potassium, and Sulfur**.

### Final Answer:
The deficiency of nitrogen, potassium, and sulfur can cause inhibition of cell division in plants.
