Bryophytes differ from pteridophytes in

Options

A. having mitospores
B. the absence of vascular tissue system
C. lacking embryo stage
D. all of the stage

Answer

### Step-by-Step Solution:

1. **Understanding Bryophytes and Pteridophytes**:
- Bryophytes are non-vascular plants, which means they do not have specialized tissues for the transport of water and nutrients.
- Pteridophytes are vascular plants, which possess specialized tissues (xylem and phloem) for the transport of water, nutrients, and food.

2. **Identifying Key Differences**:
- One of the most significant differences between bryophytes and pteridophytes is the presence or absence of vascular tissue.
- Bryophytes lack vascular tissues (xylem and phloem), while pteridophytes have a well-developed vascular system.

3. **Examining Other Options**:
- The options provided include:
- A) Having mitospores
- B) Absence of vascular tissue system
- C) Lacking embryo stage
- D) All of the stages
- Both bryophytes and pteridophytes produce spores, and they do not have a true embryo stage in the same sense as higher plants.

4. **Conclusion**:
- The correct answer is B) Absence of vascular tissue system. This is the main distinguishing feature between bryophytes and pteridophytes.
