Cork cambium is commonly called as phelogen. It is

Options

A. Primary meristem
B. secondary meristem
C. apical meristem
D. intercalary meristem

Answer

**Step-by-Step Solution:**

1. **Understanding Cork Cambium**: Cork cambium, also known as phloem, is a type of meristematic tissue found in plants. It plays a crucial role in the secondary growth of stems and roots.

2. **Types of Meristems**: Meristems are classified based on their origin and position. The main types include:
- **Primary Meristem**: Responsible for the primary growth of the plant, leading to an increase in length.
- **Secondary Meristem**: Involved in secondary growth, which increases the thickness or girth of the plant.
- **Apical Meristem**: Located at the tips of roots and shoots, facilitating vertical growth.
- **Intercalary Meristem**: Found between permanent tissues, contributing to growth in length after cutting or grazing.

3. **Cork Cambium Classification**:
- Cork cambium arises from the epidermis, which is a type of permanent tissue.
- Since cork cambium develops from permanent cells that regain the ability to divide, it is classified as a **secondary meristem**.

4. **Position of Cork Cambium**:
- Cork cambium is located laterally in the plant, meaning it is situated parallel to the sides of the stems and roots. This makes it a **lateral meristem**.

5. **Conclusion**: Based on the origin and position, cork cambium is classified as a **secondary meristem** and is also a **lateral meristem**.

**Final Answer**: Cork cambium is commonly called phloem, and it is a secondary meristem.
