Primary vascular tissue are formed from __________

Options

A. vascular cambium
B. phellogen
C. procambium
D. protoderm

Answer

To answer the question "Primary vascular tissue are formed from __________," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Primary Vascular Tissue**:
- Primary vascular tissues in plants consist of primary xylem and primary phloem. These tissues are responsible for the transport of water, nutrients, and food throughout the plant.

2. **Identifying the Source of Formation**:
- Primary vascular tissues are derived from specific meristematic tissues. The key to answering the question lies in identifying which meristematic tissue gives rise to these primary vascular tissues.

3. **Exploring the Options**:
- The options provided are:
1. Vascular cambium
2. Phallogen
3. Procambium
4. Protoderm

4. **Analyzing Each Option**:
- **Vascular Cambium**: This is a secondary meristem that produces secondary xylem and phloem, not primary.
- **Phallogen**: This is involved in the formation of cork and is not related to vascular tissues.
- **Procambium**: This is a primary meristematic tissue that directly gives rise to primary xylem and phloem.
- **Protoderm**: This is the outermost layer that gives rise to the epidermis, not vascular tissue.

5. **Conclusion**:
- Based on the analysis, the correct answer is **Procambium**. It is the meristematic tissue responsible for the formation of primary vascular tissues (xylem and phloem).

### Final Answer:
Primary vascular tissue are formed from **Procambium**.
