Perblem produces

Options

A. Cortex
B. Pericycle
C. Vascular strand
D. Both 1 and 2

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks what the tissue named "peribulum" produces. To answer this, we need to refer to the histogen theory, which categorizes the different layers of the shoot apical meristem.

2. **Histogen Theory Overview:**
According to the histogen theory, the shoot apical meristem is divided into three distinct meristematic zones:
- **Dermatogen:** This is the outermost layer that forms the epidermis.
- **Peribulum:** This is the middle layer that is responsible for forming the cortex and endodermis.
- **Pleurome:** This is the innermost layer that forms the vascular tissues, specifically secondary xylem and secondary phloem.

3. **Identifying the Role of Peribulum:**
Since the question specifically asks about the peribulum, we focus on its function. The peribulum is responsible for producing:
- **Cortex**
- **Endodermis**

4. **Analyzing the Options:**
The options provided are:
- Option 1: Cortex
- Option 2: Pericycle
- Option 3: Vascular strand
- Option 4: Both 1 and 2

From our understanding, we know that the peribulum produces cortex and endodermis. However, the pericycle is not produced by the peribulum; it is a different structure associated with the vascular system.

5. **Conclusion:**
Since the peribulum produces cortex and endodermis, the correct answer is Option 1: Cortex.

**Final Answer:**
The peribulum produces cortex.
