Select the incorrect statement w.r.t. meristem

Options

A. It is a group of immature cells
B. It is the area of active cell division in a plant
C. It is responsible for the formation of primary plant body
D. Lateral meristems occur in all plants

Answer

To solve the question of selecting the incorrect statement with respect to meristems, we will analyze each of the given options step by step.

### Step-by-Step Solution:

1. **Understanding Meristems**:
- Meristems are regions in plants consisting of undifferentiated cells that are capable of division. They play a crucial role in plant growth.

2. **Analyzing the Options**:
- **Option 1**: "It is a group of immature cells."
- This statement is **correct**. Meristems consist of immature cells that can divide and differentiate into various types of plant tissues.

- **Option 2**: "It is the area of active cell degeneration in plants."
- This statement is **incorrect**. Meristems are areas of active cell division, not degeneration. Therefore, this option is not true.

- **Option 3**: "It is responsible for the formation of primary plant body."
- This statement is **correct**. The apical meristems are responsible for the growth of the primary plant body, contributing to the lengthening of roots and shoots.

- **Option 4**: "Lateral meristem occurs in all plants."
- This statement is **incorrect**. Not all plants possess lateral meristems. For example, palm trees do not have lateral meristems, which are responsible for secondary growth.

3. **Conclusion**:
- The incorrect statements are Options 2 and 4. However, since the question asks for a single incorrect statement, the most relevant incorrect statement regarding meristems is **Option 4**: "Lateral meristem occurs in all plants."

### Final Answer:
The incorrect statement with respect to meristem is **Option 4**: "Lateral meristem occurs in all plants."
