Minerals known to be required in large amounts for plant growth include

Options

A. calcium, magnesium, manganese, copper
B. potassium, phosphorus, selenium, boron
C. magnesium, sulphur, iron, zinc
D. phosphorus , potassium, sulphur, calcium

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Nutrient Classification:**
- Nutrients required by plants are classified into two main categories: macronutrients and micronutrients.
- Macronutrients are needed in larger amounts (more than 10 mMol per kg of dry matter), while micronutrients are needed in smaller amounts (less than 10 mMol per kg of dry matter).

2. **Identifying Macronutrients:**
- Common macronutrients include:
- Carbon (C)
- Oxygen (O)
- Hydrogen (H)
- Nitrogen (N)
- Phosphorus (P)
- Potassium (K)
- Calcium (Ca)
- Sulfur (S)
- Magnesium (Mg)

3. **Identifying Micronutrients:**
- Common micronutrients include:
- Iron (Fe)
- Manganese (Mn)
- Boron (B)
- Copper (Cu)
- Zinc (Zn)
- Chloride (Cl)
- Nickel (Ni)
- Cobalt (Co)
- Sodium (Na)
- Silicon (Si)

4. **Selecting the Correct Answer:**
- The question asks for minerals required in large amounts for plant growth.
- From the list of macronutrients, we can identify that phosphorus, potassium, sulfur, and calcium are included.
- Therefore, the correct answer is option number four, which includes phosphorus, potassium, sulfur, and calcium as they are all macronutrients.

5. **Conclusion:**
- The minerals required in large amounts for plant growth are phosphorus, potassium, sulfur, and calcium.
