Which statement is true about bryophytes ?

Options

A. They are non-photosynthetic
B. Zygote produces gametophyte on germination
C. Spores form gametophyte plant on germination
D. They have vascular tissue

Answer

To determine which statement is true about bryophytes, let's analyze each option step by step:

1. **Understanding Bryophytes**: Bryophytes are non-vascular plants that include mosses, liverworts, and hornworts. They are characterized by their life cycle, which includes a dominant gametophyte stage.

2. **Evaluating the Statements**:
- **Statement 1**: "They are known photosynthetic."
- **Analysis**: While bryophytes are indeed photosynthetic, this statement is vague and does not provide specific information about their reproductive processes or structures.

- **Statement 2**: "Zygote produces gametophyte on germination."
- **Analysis**: This statement is incorrect. In bryophytes, the zygote develops into a sporophyte, not a gametophyte. The sporophyte then produces haploid spores, which can germinate to form gametophytes.

- **Statement 3**: "Spores from gametophyte plant on germination."
- **Analysis**: This statement is correct. The spores produced by the sporophyte (which is attached to the gametophyte) can germinate to form new gametophyte plants.

- **Statement 4**: "They have vascular tissue."
- **Analysis**: This statement is incorrect. Bryophytes do not have vascular tissues (xylem and phloem), which distinguishes them from higher plants.

3. **Conclusion**: The only true statement about bryophytes is that "Spores from gametophyte plant on germination" (Statement 3).

### Final Answer:
The correct statement about bryophytes is: **"Spores from gametophyte plant on germination."**
