Division "Tracheophyta" includes :-

Options

A. Bryophyta
B. All vascular plants
C. All non-vascular plants
D. All non-vascular and vascular plants

Answer

### Step-by-Step Solution:

1. **Understanding the Division "Tracheophyta":**
- The division "Tracheophyta" refers to a group of plants that possess vascular tissues. These vascular tissues are essential for the transport of water, nutrients, and food throughout the plant.

2. **Identifying Vascular vs. Non-Vascular Plants:**
- Vascular plants (Tracheophyta) include those that have specialized tissues known as xylem and phloem. Xylem is responsible for the conduction of water and minerals, while phloem transports food.
- Non-vascular plants, such as bryophytes (e.g., mosses), do not have these specialized tissues and rely on diffusion for the movement of substances.

3. **Categories of Vascular Plants:**
- Vascular plants are further divided into three main groups:
- **Pteridophyta:** This group includes ferns and their relatives.
- **Gymnosperms:** These are seed-producing plants that do not form flowers or fruits (e.g., conifers).
- **Angiosperms:** This group consists of flowering plants that produce seeds enclosed within a fruit.

4. **Conclusion:**
- Since the question asks what the division "Tracheophyta" includes, the correct answer is that it includes all vascular plants. Therefore, the correct option is **B: all vascular plants**.
