The first cell of sporophytic generation in bryophyta is:-

Options

A. Spore
B. Spore mother cell
C. Zygote
D. Protonema

Answer

To answer the question about the first cell of the sporophytic generation in bryophyta, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Generations**:
- In bryophytes, there are two main generations: the gametophytic generation and the sporophytic generation. The gametophyte is haploid (n), while the sporophyte is diploid (2n).

2. **Formation of Zygote**:
- The sporophytic generation begins with the formation of a zygote. This zygote is formed when male and female gametes (which are haploid) fuse together.

3. **Zygote Development**:
- The zygote, being diploid (2n), undergoes development to form the sporophyte. This is the first cell of the sporophytic generation.

4. **Role of Spores**:
- The sporophyte will eventually produce spores through meiosis. However, the spores themselves do not initiate the sporophytic generation; they are produced by it.

5. **Conclusion**:
- Therefore, the first cell of the sporophytic generation in bryophyta is the zygote.

### Final Answer:
The first cell of the sporophytic generation in bryophyta is the **zygote**.
