In bryophytes meiosis occurs in -

Options

A. Spores
B. Gametes mother cells
C. Gametes
D. Spore mother cells in capsule / sporophyte / sporogonium

Answer

To answer the question "In bryophytes meiosis occurs in -", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Bryophytes**:
- Bryophytes are non-vascular plants that include mosses and liverworts. They are known as amphibians of the plant kingdom because they require water for sexual reproduction.

2. **Life Cycle of Bryophytes**:
- The life cycle of bryophytes alternates between two generations: the gametophyte (haploid) and the sporophyte (diploid).
- The main plant body of bryophytes is the gametophyte, which produces gametes.

3. **Formation of Zygote**:
- When gametes (male and female) fuse, they form a diploid zygote. This zygote develops into the sporophyte.

4. **Sporophyte Development**:
- The sporophyte is multicellular and diploid. It is dependent on the gametophyte for nutrition.

5. **Meiosis in Bryophytes**:
- Meiosis occurs in the sporophyte generation, specifically in the spore mother cells (also known as sporogenous cells) found in the capsule of the sporophyte.
- This process of meiosis results in the production of haploid spores.

6. **Conclusion**:
- Therefore, in bryophytes, meiosis occurs in the sporophyte, specifically in the spore mother cells located in the capsule of the sporophyte.

### Final Answer:
In bryophytes, meiosis occurs in the sporophyte, specifically in the spore mother cells located in the capsule.
