Epidermal tissue system is derived from

Options

A. protoderm
B. procambium
C. periblem
D. plerome

Explanation

To answer the question "Epidermal tissue system is derived from," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Epidermal Tissue System**: The epidermal tissue system is the outermost layer of cells in a plant. It serves several functions, including protection against environmental factors and regulation of gas exchange through structures called stomata.

2. **Identifying the Source of Epidermal Tissue**: The epidermal tissue system is derived from specific tissue layers during the development of the plant. In plants, tissues are categorized based on their origin during embryonic development.

3. **Recognizing the Types of Meristematic Tissues**: There are three primary types of meristematic tissues in plants:
- Protoderm: This is the outermost layer that gives rise to the epidermis.
- Procambium: This gives rise to vascular tissues (xylem and phloem).
- Pericycle: This is involved in the formation of lateral roots.
- Pleurome: This is not a standard term used in plant anatomy.

4. **Selecting the Correct Answer**: Among the options provided, the protoderm is the correct answer as it specifically gives rise to the epidermal tissue system.

5. **Conclusion**: Therefore, the epidermal tissue system is derived from the protoderm.

### Final Answer:
The epidermal tissue system is derived from the protoderm.
