Interfascicular cambium and cork cambium are formed due to

Options

A. cell division
B. cell differentiation
C. cell dedifferentiation
D. redifferentiation

Explanation

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the formation of interfascicular cambium and cork cambium. We need to identify the biological process responsible for their formation.

2. **Analyzing the Options**:
- **Option 1: Cell Division**: This option suggests that interfascicular cambium and cork cambium are formed due to cell division. However, this is incorrect because cell division (mitosis or meiosis) does not directly lead to the formation of these cambiums.

- **Option 2: Cell Differentiation**: This option states that these cambiums are formed due to cell differentiation. While differentiation is a process where cells mature, it does not specifically account for the formation of cambiums.

- **Option 3: Cell De-differentiation**: This option suggests that interfascicular cambium and cork cambium are formed due to cell de-differentiation. This is the correct answer. De-differentiation refers to mature cells regaining the ability to divide, which is essential for cambium formation.

- **Option 4: Re-differentiation**: This option refers to the process where de-differentiated cells mature again into specialized cells. While this is a relevant process, it does not directly explain the formation of cambiums.

3. **Conclusion**: The correct answer is that interfascicular cambium and cork cambium are formed due to **cell de-differentiation**. This process allows mature cells to regain the ability to divide, leading to the formation of cambium tissues.
