Find out the incorrect statement .

Options

A. Virus free plant can be obtained by meristem culture.
B. In micro - propagation somaclones are produced.
C. A living plant cell whose cell wall is removed is known as protoplast.
D. none

Answer

To solve the question "Find out the incorrect statement," we will analyze each statement provided in the context of plant biology and tissue culture.

### Step-by-Step Solution:

1. **Analyze Statement 1**: "The virus-free plant can be obtained by meristem culture."
- **Explanation**: Meristem culture is a technique used to propagate plants. The meristematic tissue is typically free from viruses, allowing for the production of virus-free plants. This statement is **correct**.

2. **Analyze Statement 2**: "In micropropagation, soma clones are produced."
- **Explanation**: Micropropagation involves taking small parts of a plant (explants) and growing them in vitro under controlled conditions. The resulting plants are indeed referred to as somaclones, which are genetically identical to the original plant. This statement is **correct**.

3. **Analyze Statement 3**: "The living plant cell whose cell wall is removed is known as a protoplast."
- **Explanation**: When the cell wall of a plant cell is removed, the remaining structure is called a protoplast. Protoplasts can be used in various biotechnological applications, including somatic hybridization. This statement is **correct**.

4. **Analyze Statement 4**: "All the statements are correct."
- **Explanation**: Since all the previous statements have been verified as correct, this statement is also **correct**.

### Conclusion:
Since all the statements provided in the question are correct, there is no incorrect statement among them. Therefore, the answer to the question is that there is no incorrect statement.

### Final Answer:
**None of the statements are incorrect.**
