Answer

To answer the question "Pteridophyta differs from bryophyta in having:", we will analyze the key characteristics of both groups of plants.

### Step-by-Step Solution:

1. **Identify the Main Plant Body**:
- **Bryophyta**: The main plant body is the gametophyte, which is **haploid**.
- **Pteridophyta**: The main plant body is the sporophyte, which is **diploid**.

2. **Presence of True Roots and Leaves**:
- **Bryophyta**: True roots and leaves are **absent**.
- **Pteridophyta**: True roots and leaves are **present**.

3. **Vascular Tissue**:
- **Bryophyta**: Vascular tissues are **absent**.
- **Pteridophyta**: Vascular tissues are **present**.

4. **Archegonia Structure**:
- **Bryophyta**: Archegonia is present with a **long neck** and consists of **six vertical rows of cells**.
- **Pteridophyta**: Archegonia is present with a **short neck** and consists of **four vertical rows of cells**.

5. **Sporophyte Dependency**:
- **Bryophyta**: The sporophyte is **capsular** and **totally dependent** on the gametophyte.
- **Pteridophyta**: The sporophyte is differentiated into **root, stem, and leaves** and is initially dependent on the gametophyte.

### Conclusion:
