Interfascicular cambium and cork cambium are

Options

A. Embryonic meristems
B. Intercalary meristems
C. Lateral meristems
D. Primary meristems

Answer

### Step-by-Step Solution:

1. **Understanding Meristems**:
- Meristems are regions of undifferentiated cells in plants that have the ability to divide and contribute to growth. They are classified into two main categories: primary and secondary meristems.

2. **Identifying Types of Meristems**:
- Primary meristems are formed early in plant development and include apical meristems (found at the tips of roots and shoots) and intercalary meristems (located at the base of leaves and stems).
- Secondary meristems, on the other hand, develop later and contribute to the growth in thickness (lateral growth) of the plant.

3. **Defining Interfascicular Cambium**:
- Interfascicular cambium is a type of secondary meristem that forms between vascular bundles (fascicles) in dicotyledonous plants. It plays a crucial role in the secondary growth of stems.

4. **Defining Cork Cambium**:
- Cork cambium, also known as phellogen, is another type of secondary meristem responsible for producing cork (phellem) and is involved in the formation of the outer protective layer of stems and roots.

5. **Categorizing Both Cambiums**:
- Both interfascicular cambium and cork cambium are classified as secondary meristems. They are also referred to as lateral meristems because they contribute to the increase in girth of the plant.

6. **Conclusion**:
- Therefore, the correct classification for both interfascicular cambium and cork cambium is that they are types of lateral meristems.

### Final Answer:
Both interfascicular cambium and cork cambium are types of lateral meristems.
