Gametic meiosis is found in all animals. In sporic meiosis the sporophyte produces sporangia where meiosis occurs producing haploid spores.

A fern plant body is sporophytic (2n) and is differentiated into roots, stems and leaves. On the ventral surface of leaves sporangia are borne in a group called sori. Inside the sporangium are present the spores which are formed by reduction duvsion. Thus the spores produced are haploid in nature and germinate to produce a prothallus that represents the gametophytic generation. Antheridium and archegonium are borne on this prothallus. Thus meiosis takes place at the stage of spore formation.

Meiosis in Ferns
Meiosis is a type of cell division that occurs in the life cycle of ferns. It is a crucial process that leads to the formation of spores, which are reproductive structures in ferns.
Formation of Spores
- In ferns, meiosis occurs when spores are formed.
- Spores are haploid reproductive structures that are produced by meiosis in the sporangia of ferns.
- These spores are released from the sporangia and are dispersed by wind or water.
Role of Spores in Ferns
- Once the spores are dispersed, they germinate to form a structure called the gametophyte.
- The gametophyte is a small, independent plant body that produces gametes.
- These gametes are then involved in sexual reproduction to produce a new sporophyte plant.
Conclusion
In the life cycle of ferns, meiosis occurs when spores are formed. This process is essential for the production of haploid spores, which eventually give rise to the gametophyte generation in ferns. Understanding the role of meiosis in the fern life cycle is crucial for comprehending the reproductive biology of these fascinating plants.
