Carl Maze (1915) divided mineral elements into two categories on the basis of

Options

A. quantity in which these are required
B. quality and action
C. toxicity they cause
D. path they travelled in plant.

Answer

**Step-by-Step Solution:**

1. **Identify the Context**: The question pertains to the classification of mineral elements in plants as proposed by Carl Mays in 1915.

2. **Understand the Basis of Classification**: Carl Mays categorized mineral elements based on the quantity in which they are required by plants. This means he looked at how much of each mineral is necessary for plant growth and development.

3. **Define the Categories**:
- **Macronutrients**: These are the minerals that plants require in larger quantities. Examples include nitrogen, phosphorus, and potassium. They play crucial roles in plant growth, biochemical reactions, and osmotic regulation.
- **Micronutrients**: These are the minerals that plants need in smaller amounts. Examples include chlorine, boron, and iron. They are essential for the effective functioning of enzymes in plants.

4. **Summarize the Importance**: Both macronutrients and micronutrients are vital for plant health. Macronutrients are primarily involved in overall growth and metabolic processes, while micronutrients support enzymatic functions and other specific roles.

5. **Conclude the Answer**: Carl Mays divided mineral elements into two categories: macronutrients (required in larger quantities) and micronutrients (required in smaller quantities).
