Bryophytes show

Options

A. asexual reproduction `&` zygotic meiosis
B. asexual reproduction `&` sporic meiosis
C. no asexual reproduction but sporic meiosis
D. gametophytic dominance and sporic meiosis

Answer

### Step-by-Step Solution:

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

2. **Life Cycle of Bryophytes**:
- The life cycle of bryophytes is haplodeplastic, meaning it alternates between haploid (gametophyte) and diploid (sporophyte) stages.
- The dominant stage in bryophytes is the gametophyte, which is haploid and independent.

3. **Reproductive Methods**:
- Bryophytes can reproduce both sexually and asexually.
- Asexual reproduction occurs through structures like gemmae or fragmentation.
- Sexual reproduction involves the formation of gametes (sperm and eggs) from the gametophyte.

4. **Formation of Zygote**:
- The sperm fertilizes the egg, forming a diploid zygote.
- The zygote develops into a sporophyte, which is dependent on the gametophyte for nutrition.

5. **Meiosis in Sporophyte**:
- The sporophyte undergoes meiosis to produce haploid spores.
- These spores can germinate to form new gametophytes, completing the cycle.

6. **Evaluating the Options**:
- **Option A**: Asexual reproduction and zygotic meiosis - Incorrect, as the zygote does not undergo meiosis.
- **Option B**: Asexual reproduction and sporic meiosis - This is partially correct, but not specific enough.
- **Option C**: No asexual reproduction but sporic meiosis - Incorrect, as bryophytes do reproduce asexually.
- **Option D**: Gametophytic dominance and sporic meiosis - Correct, as it accurately describes the dominant stage and the process of spore formation.

7. **Conclusion**:
- The correct answer is **gametophytic dominance and sporic meiosis**. This option encapsulates the key characteristics of bryophytes.
