A fern differs from a moss in having
1 Swimming archegonia
2 Swimming antherozoids
3 Independent gametophytes
4 Independent sporophytes
Explanation:
Ferns contain a dominant sporophyte whereas mosses contain a dominant gametophyte. By sporophyte dominant it means that the sporopyte is larger and lives a longer time than the gametophytic generation. Fern and moss both have swimming antherozoids. They swim in the water and fertilise with the egg of the archegonium.

1 bract
2 ligule
3 petiole
4 spathe
Explanation:
The development of megaspores and microspores two different spore size is known as heterospory. It is true of bryophytes. Some pteridophytes, including selaginella, are where heterospory first appeared. Its common names Include clubmoss and spike moss. On the adaxial side of its leaves the ligules is an outgrowth that resembles to a flap.
Ferns contain a dominant sporophyte whereas mosses contain a dominant gametophyte. By sporophyte dominant it means that the sporopyte is larger and lives a longer time than the gametophytic generation. Fern and moss both have swimming antherozoids.
