Conclusion

Content: A spore capsule comprises a layer of sterile cells, second layer of elaters that are hygroscopic or absorbs moisture from the surrounding. The hydrogroscopic movement of the cells within the spore capsule results in flicking of the spores upward and outward. Unfortunately, the spore capsule ruptures, as the spores attain maturity and move freely in the environment as dormant spores. The life cycle of bryophyte continues once the dormant spore starts germinating into protonema. Conclusion
Therefore, we can conclude that the gametophyte phase contains haploid cells that possess an unpaired number of chromosomes. In contrast, the saprophyte phase includes diploid cells that possess two sets of paired chromosomes. Gametophyte phase occurs predominantly in all the bryophytes and lasts longer.
