Dermatogen gives rise to

Options

A. Cortex
B. Epidermis
C. Stele
D. Root cap

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks what the dermatogen gives rise to in the context of plant histology.

2. **Histogen Theory**: The histogen theory, proposed by J. Hansen, describes the organization of the apical meristem in plants. It divides the meristem into three distinct layers, each responsible for forming different parts of the plant.

3. **Identifying the Layers**: The three layers identified in the histogen theory are:
- **Dermatogen**: The outermost layer.
- **Periblam**: The middle layer.
- **Pleurom**: The innermost layer.

4. **Function of Dermatogen**: The dermatogen is specifically responsible for giving rise to the epidermis of the stem and other aerial parts of the plant.

5. **Conclusion**: Therefore, the dermatogen gives rise to the epidermis.

6. **Final Answer**: The answer to the question is that dermatogen gives rise to the epidermis of the stem and other aerial parts.
