Stelar tissue originate from

Options

A. Dematogen
B. Plerome
C. Periblem
D. Tunica layer

Answer

To answer the question "Stelar tissue originate from," we need to analyze the options provided: Dermatogen, Plerome, Periblem, and Tunica.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Dermatogen**: This is the outermost layer of the plant meristem. It primarily gives rise to the epidermis, which is the protective outer layer of the plant.
- **Periblem**: This is the middle layer of the plant meristem. It contributes to the formation of the cortex and also the epidermis.
- **Plerome**: This is the innermost layer of the plant meristem. It is responsible for giving rise to the vascular tissues, which include xylem and phloem, as well as the pith.
- **Tunica**: This term generally refers to the outer layer of the shoot apical meristem but is not specifically related to the formation of stelar tissues.

2. **Analyzing Each Option**:
- **Dermatogen**: Since it gives rise to the epidermis, it does not originate stelar tissue. **(Incorrect)**
- **Periblem**: This layer contributes to the cortex and epidermis, but not to stelar tissues. **(Incorrect)**
- **Plerome**: This layer is responsible for the development of vascular tissues, which are indeed part of the stelar tissue. **(Correct)**
- **Tunica**: This layer is not related to the formation of stelar tissues. **(Incorrect)**

3. **Conclusion**: Based on the analysis, the correct answer is **Plerome**, as it is the layer responsible for the formation of stelar tissues.

### Final Answer:
Stelar tissue originates from **Plerome**.
