Assertion: Somaclonal variations produce slight differences in plant.
Reason: They are produced while performing tissue culture.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reson are true but reason is not the correct explanation of assertion.
C. if assertion is true but reason is false.
D. If both assertion and reason are false.

Answer

To solve the assertion and reason question, we will analyze both the assertion and the reason step by step.

### Step 1: Understand the Assertion
The assertion states that "Somaclonal variations produce slight differences in plants."
- Somaclonal variations refer to the genetic variations that can occur in plants that are produced through tissue culture.
- However, these variations are often minimal and do not lead to significant differences when compared to the parent plant.

### Step 2: Understand the Reason
The reason states that "They are produced while performing tissue culture."
- Somaclonal variations indeed arise during the process of tissue culture or micropropagation.
- Tissue culture involves growing plant cells or tissues in a controlled environment, which can lead to genetic variations.

### Step 3: Evaluate the Truth of the Assertion
- The assertion is misleading. While somaclonal variations can occur, they typically do not produce "slight differences" in the sense that they are often very similar to the parent plant. Thus, the assertion is **not correct**.

### Step 4: Evaluate the Truth of the Reason
- The reason is correct; somaclonal variations are produced during tissue culture.

### Step 5: Determine the Relationship
- Since the assertion is false and the reason is true, the correct conclusion is that the assertion does not support the reason.

### Final Conclusion
The correct answer to the question is option D: The assertion is false, and the reason is true.
