Answer

To determine the correct sequence of events in the life cycle of Bryophytes, we can break down the process step by step:

1. **Germination of Spores (I)**: The life cycle begins with the germination of spores. Spores are produced by the sporophyte through meiosis and are released into the environment. When conditions are favorable, these spores germinate to form a new structure.

2. **Formation of Gametophyte (III)**: After germination, the spores develop into a gametophyte. The gametophyte is the dominant phase in the life cycle of bryophytes and is haploid (n).

3. **Formation of Gametes (II)**: The gametophyte produces gametes. Male gametes are produced in the antheridia, and female gametes are produced in the archegonia. This process involves the development of specialized structures for reproduction.

4. **Fertilization of Gametes to Form an Embryo (IV)**: The male gametes (antherozoids) swim through water to reach the female gametes (eggs) in the archegonia. Fertilization occurs when the male gamete fuses with the female gamete, resulting in the formation of a diploid zygote.

5. **Formation of Sporophyte (V)**: The zygote develops into a sporophyte, which is also diploid (2n). The sporophyte remains attached to the gametophyte and eventually produces spores through meiosis, completing the cycle.

Thus, the correct sequence of events in the life cycle of Bryophytes is:
**(I) Germination of spores → (III) Formation of gametophyte → (II) Formation of gametes → (IV) Fertilization of gametes to form an embryo → (V) Formation of sporophyte.**

### Final Sequence:
1. Germination of spores (I)
2. Formation of gametophyte (III)
3. Formation of gametes (II)
4. Fertilization of gametes to form an embryo (IV)
5. Formation of sporophyte (V)
