The correct Answer is:
To solve the question regarding the correct sequence of events in the cycle of Bryophytes, we need to analyze the life cycle of these plants step by step. Here’s the breakdown of the events: ### Step-by-Step Solution: 1. **Germination of Spores (I)**: The life cycle of Bryophytes begins with the germination of spores. Spores are produced by the sporophyte through meiosis and when conditions are favorable, they germinate to form a young gametophyte. 2. **Formation of Gametophyte (III)**: After germination, the spores develop into a gametophyte. This structure is haploid and is responsible for the sexual phase of the life cycle. 3. **Formation of Gametes (II)**: The gametophyte then undergoes mitosis to produce gametes. Male gametes are formed in the antheridia, and female gametes are formed in the archegonia. 4. **Fertilization of Gametes to Form an Embryo (IV)**: When the male gametes (sperms) swim to the female gametes (eggs), fertilization occurs, resulting in the formation of a diploid zygote, which eventually develops into an embryo. 5. **Formation of Sporophyte (V)**: The zygote grows into a sporophyte, which is the diploid generation of Bryophytes. The sporophyte will eventually produce spores through meiosis, thus continuing the cycle. ### Correct Sequence: The correct sequence of events in the life cycle of Bryophytes is: 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) ### Final Answer: The correct option with the sequence is: **I → III → II → IV → V**
