Xylem and phloem of primary plant body are formed from

Options

A. Dermatogen
B. Protoderm
C. Promeristem
D. Procambium

Answer

**Step-by-Step Solution:**

1. **Identify the Types of Meristems**: In the primary plant body, there are three types of primary meristems: protoderm, ground meristem, and procambium.

2. **Understand the Role of Each Meristem**:
- **Protoderm**: This meristem gives rise to the epidermis, which is the outer protective layer of the plant.
- **Ground Meristem**: This meristem develops into ground tissues, which consist of parenchyma, collenchyma, and sclerenchyma. These tissues are responsible for storage, support, and photosynthesis.
- **Procambium**: This is the meristem that specifically develops into vascular tissues.

3. **Focus on Vascular Tissue Formation**: The vascular tissue is crucial for the transport of water, nutrients, and food throughout the plant. It is composed of xylem and phloem.

4. **Conclusion**: The xylem and phloem of the primary plant body are formed from the procambium.

5. **Select the Correct Answer**: Among the given options, the correct answer is **procambium (Option D)**, as it is the meristem responsible for the formation of vascular tissues, including xylem and phloem.
