Epiblema of roots is equivalent to
(a) Pericycle
(b) Endodermis
(c) Epidermis
(d) Stele

Answer

To determine what the epiblema of roots is equivalent to, we need to analyze the characteristics of epiblema and compare it with the options provided.

### Step-by-Step Solution:

1. **Understanding Epiblema**:
- The epiblema is a layer found in the roots of plants, particularly in monocots. It is the outermost layer of the root.

2. **Characteristics of Epiblema**:
- The epiblema is typically a single layer of cells.
- It is composed of thin-walled cells, which are usually living cells.
- Root hairs arise from the epiblema, aiding in water and nutrient absorption.

3. **Comparing with Options**:
- **(a) Pericycle**: This is a layer of cells located just inside the endodermis and is involved in the formation of lateral roots. It does not have the same function or structure as epiblema.
- **(b) Endodermis**: This is the innermost layer of the cortex in roots, which regulates the flow of water and nutrients into the vascular system. It is not equivalent to epiblema.
- **(c) Epidermis**: The epidermis is the outermost layer of cells in the root of dicots, which is also made up of thin-walled living cells and can produce root hairs. This is very similar to the function and structure of epiblema.
- **(d) Stele**: The stele refers to the central part of the root that contains the vascular tissue. It is not equivalent to epiblema.

4. **Conclusion**:
- Based on the analysis, the epiblema of roots is equivalent to the epidermis of dicot roots. Therefore, the correct answer is **(c) Epidermis**.
