cork cambium is also called

Options

A. phelloderm
B. Phellem
C. Periderm
D. Phellogen

Answer

**Step-by-Step Solution:**

1. **Understanding Cork Cambium**: Cork cambium is a type of lateral meristem that is responsible for the production of cork cells, which are part of the outer protective layer of a plant.

2. **Identifying Alternative Names**: Cork cambium is also known by another name. In this case, it is referred to as "phallogen."

3. **Formation of Cork Cells**: Cork cambium is formed from the re-differentiation of cork cells (also called phelum). This process is essential for the growth and protection of the plant.

4. **Relationship with Other Structures**: Cork cambium (phallogen) gives rise to the phalloderm, which is the secondary cortex. This indicates that cork cambium is part of a larger system involving other tissues.

5. **Eliminating Incorrect Options**:
- Phalloderm is known as the secondary cortex (incorrect).
- Phelum refers to cork cells (incorrect).
- Periderm encompasses all three structures (cork cambium, cork cells, and secondary cortex) but is not the direct name for cork cambium (incorrect).

6. **Conclusion**: The correct answer is that cork cambium is also called "phallogen."

**Final Answer**: Cork cambium is also called "phallogen."
