The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Haplontic Life Cycle**: - In the haplontic life cycle, the dominant phase is the haploid gametophyte. The zygote, which is diploid, is formed after the fusion of gametes. 2. **Formation of the Zygote**: - The zygote undergoes meiosis, not mitosis. This is a key characteristic of the haplontic life cycle. 3. **Meiosis in the Zygote**: - During meiosis, the diploid zygote produces haploid spores. This is an essential step in the life cycle. 4. **Germination of Spores**: - The haploid spores then germinate to form the gametophyte generation. 5. **Gametogenesis**: - The gametophyte produces gametes through the process of gametogenesis. 6. **Syngamy**: - The gametes fuse during syngamy to form a new diploid zygote, completing the cycle. 7. **Identifying the Correct Statement**: - The statements provided need to be evaluated based on the understanding of the haplontic life cycle: - **Statement 1**: Incorrect - Zygote undergoes meiosis, not mitosis. - **Statement 2**: Correct - Meiosis in the zygote results in the formation of haploid spores. - **Statement 3**: Incorrect - Spores produced are haploid, not diploid. 8. **Conclusion**: - The correct statement regarding the haplontic life cycle is that meiosis occurs in the zygote, resulting in the formation of haploid spores.
