Vascular tissues in flowering plants develop from

Options

A. phellogen
B. plerome
C. periblem
D. dermatogen

Explanation

To answer the question "Vascular tissues in flowering plants develop from," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Vascular Tissues**: Vascular tissues in flowering plants consist of xylem and phloem, which are responsible for the transport of water, nutrients, and food throughout the plant.

2. **Identifying the Source of Vascular Tissues**: Vascular tissues develop from specific types of meristematic tissues. Meristematic tissues are regions in plants where cells are actively dividing.

3. **Types of Primary Meristems**: The primary meristems include:
- **Dermatogen**: This is the outermost layer that forms the epidermis.
- **Periblem**: This forms the cortex of the plant.
- **Pleurome**: This is the central core that gives rise to the stele, which includes vascular tissues.

4. **Focus on Pleurome**: The part of the pleurome that specifically gives rise to vascular tissues is known as **procambium**. Therefore, vascular tissues develop from the procambium, which is a part of the pleurome.

5. **Conclusion**: Thus, the correct answer to the question is that vascular tissues in flowering plants develop from **pleurome**.

### Final Answer:
Vascular tissues in flowering plants develop from pleurome.
