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 solve the question of which element is not present in plant tissues in large amounts, we can follow these steps:

### Step 1: Understand the Classification of Nutrients
Plants require various nutrients for their growth, which are classified into two categories: macronutrients and micronutrients.

### Step 2: Identify Macronutrients
Macronutrients are required in larger quantities and include:
- Carbon (C)
- Hydrogen (H)
- Nitrogen (N)
- Oxygen (O)
- Phosphorus (P)
- Potassium (K)
- Magnesium (Mg)
- Calcium (Ca)
- Sulfur (S)

### Step 3: Identify Micronutrients
Micronutrients are required in smaller amounts and include:
- Molybdenum (Mo)
- Boron (B)
- Chlorine (Cl)
- Copper (Cu)
- Zinc (Zn)
- Nickel (Ni)
- Manganese (Mn)

### Step 4: Analyze the Options
Now, let's analyze the options given in the question:
- A. Carbon
- B. Hydrogen
- C. Molybdenum
- D. Sulphur

From our classification:
- Carbon and Hydrogen are macronutrients, required in large amounts.
- Sulfur is also a macronutrient, needed in significant quantities.
- Molybdenum, on the other hand, is a micronutrient, which means it is required in smaller amounts.

### Step 5: Conclusion
Based on the analysis, the element that is not present in plant tissues in large amounts is **C. Molybdenum**.

### Final Answer
**C. Molybdenum**
