Epiblema in roots is derived from

Options

A. Protoderm
B. Procabmium
C. Ground meritem
D. Calyptrogen

Answer

To determine the origin of epiblema in roots, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Epiblema**:
- Epiblema is the outermost layer of cells in the roots. It plays a crucial role in protecting the root and facilitating the absorption of water and nutrients.

2. **Identify the Options**:
- The options given are:
- A) Protoderm
- B) Procambium
- C) Ground meristem
- D) Caliprogen

3. **Analyze Each Option**:
- **A) Protoderm**: This is a type of primary meristem that gives rise to the outer layer of cells in both roots and stems. It is responsible for forming the epidermis in stems and the epiblema in roots.
- **B) Procambium**: This meristematic tissue gives rise to vascular tissues, specifically primary xylem and primary phloem, and is not involved in forming the outer layer of roots.
- **C) Ground meristem**: This tissue gives rise to ground tissues such as parenchyma, colenchyma, and sclerenchyma, which are not related to the formation of epiblema.
- **D) Caliprogen**: This layer of rapidly dividing cells is located at the root tip and contributes to the formation of the root cap, not the epiblema.

4. **Conclude the Correct Answer**:
- Based on the analysis, the epiblema in roots is derived from the **protoderm**.

### Final Answer:
The epiblema in roots is derived from **protoderm**.
