The mineral needed by plants to make proteins is :

Options

A. neon
B. iodine
C. nitrogen
D. calcium

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks for the mineral that plants need to make proteins.

2. **Identify the Options**: The options provided are Neon, Iodine, Nitrogen, and Calcium.

3. **Recall Plant Nutrition**: Plants require various minerals for their growth and development, categorized into macronutrients (needed in larger quantities) and micronutrients (needed in smaller quantities).

4. **Focus on Protein Synthesis**: To make proteins, plants need specific nutrients. Proteins are made up of amino acids, which are the building blocks of proteins.

5. **Identify the Key Mineral**: Among the options, Nitrogen is known to be essential for the synthesis of amino acids. When plants absorb Nitrogen from the soil, it is transformed into amino acids.

6. **Conclusion**: Since amino acids are crucial for protein formation, the mineral needed by plants to make proteins is **Nitrogen**.

**Final Answer**: The mineral needed by plants to make proteins is **Nitrogen**.
