Pteridophytes differ from bryophytes in having

Options

A. Archegonium
B. Vascular bundle
C. Motile antherozoids
D. Alternation of generation

Answer

**Step-by-Step Solution:**

1. **Understanding the Groups:**
- Pteridophytes and bryophytes are both groups of plants that belong to the category known as cryptogams, which are primitive plants that do not produce seeds or flowers.

2. **Identifying Key Features:**
- Both groups have male and female sex organs. The male sex organ is called antheridium, and the female sex organ is called archegonium.

3. **Vascular Tissue Comparison:**
- A major difference between the two groups is the presence of vascular tissues. Bryophytes are non-vascular plants, meaning they lack vascular tissues (xylem and phloem) that are essential for the transport of water and nutrients.
- In contrast, pteridophytes have well-developed vascular tissues, allowing them to transport water and nutrients more efficiently.

4. **Life Cycle:**
- Both pteridophytes and bryophytes exhibit a haplodiplontic life cycle, which includes both gametophyte and sporophyte stages. This means they alternate between these two forms during their life cycle.

5. **Conclusion:**
- The primary difference between pteridophytes and bryophytes is that pteridophytes possess vascular tissues, while bryophytes do not.

**Final Answer:**
Pteridophytes differ from bryophytes in having vascular tissues.
