Examples of lateral meristems are

Options

A. phellogen and procambium
B. fascicular cambium and procambium
C. procambium and dermatogen
D. fascicular cambium and cork cambium

Answer

To answer the question about examples of lateral meristems, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Lateral Meristems**:
- Lateral meristems are responsible for the secondary growth in plants, which increases the thickness of stems and roots.

2. **Identifying Types of Lateral Meristems**:
- The two main types of lateral meristems are:
- **Vascular Cambium**: This produces secondary xylem (wood) and secondary phloem (part of the bark).
- **Cork Cambium**: This produces cork, which is part of the outer protective layer of the plant.

3. **Evaluating the Options**:
- The options provided in the question are:
1. Fallogen and procambium
2. Fascicular cambium and procambium
3. Procambium and dermatogen
4. Fascicular cambium and cork cambium

4. **Analyzing Each Option**:
- **Option 1**: Fallogen (another name for cork cambium) and procambium (a primary meristem, not lateral).
- **Option 2**: Fascicular cambium (a part of vascular cambium) and procambium (not lateral).
- **Option 3**: Procambium (not lateral) and dermatogen (part of apical meristem, not lateral).
- **Option 4**: Fascicular cambium (a lateral meristem) and cork cambium (another lateral meristem).

5. **Conclusion**:
- The correct answer is **Option 4: Fascicular cambium and cork cambium**, as both are examples of lateral meristems.
