Cork cambium is a

Options

A. Lateral meristem
B. Apical meristem
C. Intercalary meristem
D. Primary meristem

Answer

**Step-by-Step Solution:**

1. **Understanding Cork Cambium**: Cork cambium is a type of tissue found in vascular plants. It plays a crucial role in the growth and development of the plant.

2. **Identifying the Type of Meristem**: Cork cambium is classified as a lateral meristem. This means it is involved in the secondary growth of the plant, which increases the girth (width) rather than the length.

3. **Location of Cork Cambium**: Cork cambium is located between the cork (outer bark) and the primary phloem (part of the vascular system). It is part of the periderm, which replaces the epidermis in mature stems and roots.

4. **Comparison with Other Meristems**:
- **Apical Meristem**: This type of meristem is responsible for the increase in length (height) of the plant and is not involved in the formation of cork cambium.
- **Intercalary Meristem**: Found at the base of leaves and internodes, this meristem also contributes to growth but does not relate to cork cambium.
- **Primary Meristem**: This includes tissues that give rise to primary growth and is not directly related to cork cambium.

5. **Conclusion**: Given the definitions and functions of the various types of meristems, cork cambium is best classified as a lateral meristem, which is responsible for secondary growth in plants, particularly in dicots.

**Final Answer**: Cork cambium is a lateral meristem.
