Root cap in monocots is derived from a histogen present at tip called

Options

A. dermatogen
B. protoderm
C. calyptrogen
D. periblem

Answer

To answer the question regarding the origin of the root cap in monocots, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding the Root Cap**: The root cap is a protective structure at the tip of the root, which helps in the growth of the root by protecting the delicate meristematic tissue behind it.

2. **Identifying Histogens**: Histogens are layers of meristematic tissue that give rise to different parts of the plant. In the context of roots, we need to identify which histogen contributes to the formation of the root cap.

3. **Evaluating the Options**:
- **Dermatogen**: This is the primary meristematic tissue that forms the outermost layer of the plant, but it does not specifically give rise to the root cap.
- **Protoderm**: This is also a meristematic tissue that gives rise to the epidermis, but it is not responsible for the root cap.
- **Caliprogen**: This is the correct option. It is a layer of rapidly dividing cells at the tip of the root from which the root cap is formed.
- **Pariblym**: This is a primary meristematic tissue that gives rise to the cortex, not the root cap.

4. **Conclusion**: Based on the evaluation of the options, the root cap in monocots is derived from the histogen called **Caliprogen**.

### Final Answer:
The root cap in monocots is derived from a histogen present at the tip called **Caliprogen**.
