Which of the following elements is not present in plant tissues in large amounts ?

Options

A. C
B. H
C. Mo
D. S

Answer

To determine which element is not present in plant tissues in large amounts, we need to categorize the elements into macronutrients and micronutrients.

### Step-by-Step Solution:

1. **Understand Macronutrients and Micronutrients**:
- Macronutrients are essential elements required by plants in large quantities for growth and development. Examples include carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur.
- Micronutrients are essential elements required in smaller amounts. Examples include iron, manganese, boron, molybdenum, copper, zinc, chlorine, nickel, cobalt, sodium, and silicon.

2. **Identify the Elements in the Options**:
- We need to look at the options provided in the question (not specified here, but we will assume some common elements).
- From the context, we can infer that options may include elements like carbon, hydrogen, molybdenum, etc.

3. **Analyze Each Element**:
- **Carbon**: A macronutrient, required in large amounts.
- **Hydrogen**: A macronutrient, required in large amounts.
- **Molybdenum**: A micronutrient, required in very small amounts.

4. **Determine the Correct Answer**:
- Since molybdenum is a micronutrient and is not present in large amounts in plant tissues, it is the correct answer to the question.

### Final Answer:
The element that is not present in plant tissues in large amounts is **Molybdenum**.
