As tracheophytes, ferns and seed plants have one thing in common

Options

A. nourishing embryo from endosperm
B. having phloem in vascular bundles
C. producing eggs in ovaries
D. produce pollen grains

Answer

**Step-by-Step Solution:**

1. **Understanding Tracheophytes**: Tracheophytes are vascular plants that include both ferns (which are seedless) and seed plants (which produce seeds). They have specialized tissues for transporting water, nutrients, and food.

2. **Identifying Key Features**: The key feature of tracheophytes is the presence of vascular tissues, specifically xylem and phloem. Xylem is responsible for transporting water and minerals, while phloem transports food and nutrients.

3. **Analyzing the Options**:
- **Option A**: Nourishing embryo from endosperm - This is specific to seed plants and does not apply to ferns.
- **Option B**: Having phloem in vascular bundle - This is a common feature of both ferns and seed plants.
- **Option C**: Producing egg in ovary - This is related to seed plants and does not apply to ferns.
- **Option D**: Produce pollen grain - This is specific to seed plants and does not apply to ferns.

4. **Conclusion**: The common feature between ferns and seed plants as tracheophytes is the presence of phloem in their vascular bundles. Therefore, the correct answer is **Option B**.
