Which of the following are not secondary metabolites in plants

Options

A. Amino acids, glucose
B. Vinblastin, curcumin
C. Rubber, gums
D. Morphine, codeine

Explanation

To determine which of the following are not secondary metabolites in plants, we first need to understand the distinction between primary and secondary metabolites.

### Step-by-Step Solution:

1. **Define Metabolites**:
- Metabolites are substances produced during metabolism. They can be classified into two main categories: primary metabolites and secondary metabolites.

2. **Identify Primary Metabolites**:
- Primary metabolites are essential for the basic functions of life. They include substances like amino acids, glucose, and nucleotides, which are directly involved in growth, development, and reproduction.

3. **Identify Secondary Metabolites**:
- Secondary metabolites are not directly involved in the normal growth, development, or reproduction of an organism. Instead, they often play roles in plant defense, pollinator attraction, or competition with other plants. Examples include alkaloids (like morphine and codeine), terpenes (like rubber), and phenolics (like curcumin).

4. **Analyze the Given Options**:
- The options provided are:
- A) Amino acids
- B) Glucose
- C) Windblasting
- D) Curcumin
- E) Rubber
- F) Gums
- G) Morphine
- H) Codeine

5. **Classify Each Option**:
- **Amino Acids**: Primary metabolite
- **Glucose**: Primary metabolite
- **Windblasting**: Secondary metabolite
- **Curcumin**: Secondary metabolite
- **Rubber**: Secondary metabolite
- **Gums**: Secondary metabolite
- **Morphine**: Secondary metabolite
- **Codeine**: Secondary metabolite

6. **Conclusion**:
- The options that are **not secondary metabolites** are **Amino acids** and **Glucose**. Therefore, the answer is A) Amino acids and B) Glucose.

### Final Answer:
Amino acids and glucose are not secondary metabolites in plants.
