Vascular bundles grow from

Options

A. Protoderm
B. Perderm
C. Ground meristem
D. Procambium

Answer

**Step-by-Step Solution:**

1. **Understand the Structure of Meristematic Tissue:**
- Meristematic tissue is responsible for the growth of plants and is divided into three primary layers: protoderm, procambium, and ground meristem.

2. **Identify the Layers of Meristematic Tissue:**
- **Protoderm:** This is the outermost layer that forms the epidermal tissue of the plant.
- **Procambium:** This layer is composed of narrow, elongated meristematic cells and is crucial for the formation of vascular bundles (xylem and phloem).
- **Ground Meristem:** This layer contributes to the formation of the ground tissue system, which consists of various types of cells, including some thick-walled cells.

3. **Focus on the Function of Each Layer:**
- The protoderm primarily forms the protective outer layer (epidermis).
- The ground meristem forms the internal tissues that support the plant.
- The procambium is specifically responsible for the development of vascular tissues.

4. **Conclude the Source of Vascular Bundles:**
- Since vascular bundles (xylem and phloem) arise from the procambium, we can conclude that vascular bundles grow from the procambium.

5. **Select the Correct Answer:**
- Based on the analysis, the correct answer to the question "Vascular bundles grow from" is **procambium**.
