Assertion : Secondary metabolites are produced in small quantities and their extraction from the plant is difficult and expensive.
Reason : Secondary metabolites can be commercially produced by using tissue culture techinque.

Options

A. if both are true with reason being correct explanation
B. both true with but reason is not correct explanation
C. assertion true but reason is wrong
D. both are wrong

Answer

To analyze the assertion and reason provided in the question, we will follow these steps:

### Step 1: Understand the Assertion
The assertion states that "Secondary metabolites are produced in small quantities and their extraction from the plant is difficult and expensive."
- **Explanation**: Secondary metabolites are indeed produced in smaller amounts compared to primary metabolites. They are not universally present in all plants but are specific to certain taxonomic groups. Their extraction is challenging due to their limited availability and the complexity of the extraction processes involved.

### Step 2: Understand the Reason
The reason states that "Secondary metabolites can be commercially produced by using tissue culture technique."
- **Explanation**: Tissue culture techniques allow for the growth of plant cells in a controlled environment, which can lead to the production of secondary metabolites on a larger scale than what is possible through traditional extraction methods from whole plants.

### Step 3: Determine the Truth Value of Each Statement
- **Assertion**: True. Secondary metabolites are indeed produced in small quantities and their extraction is difficult and expensive.
- **Reason**: True. Tissue culture techniques can be used to produce secondary metabolites commercially.

### Step 4: Analyze the Relationship Between the Assertion and Reason
- The assertion is true, and the reason is also true. However, the reason does not directly explain why the assertion is true. The assertion discusses the challenges of extraction and production, while the reason discusses a method that can help produce these metabolites. Therefore, the reason does not serve as a correct explanation for the assertion.

### Conclusion
Both the assertion and reason are true, but the reason is not the correct explanation for the assertion.

### Final Answer
Both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
