In gymnosperms and angiosperms, seeds disperse the stage of the life cycle and in mosses and ferns, spores disperse the stage of the life cycle.

The correct answer is - sporophyte and gametophyte.

Explanation:

In seed producing plants such as gymnosperm and angiosperms the sporphytic part of life cycle is more dominant than the gametophytic part of life cycle. Sporophyte life cycle arise just after the formation of the zygote formation from fertilization of the gametes. The seeds are sporophytic structure that are dispersed to grow and be a full sporophytic plant with root, stem and leaves.

In mosses and ferns the case is different as there are no seed forming present the spores that are gametophytic as has n number of chromosome disperse to produce gametophytic plants that are comparatively small to sporophytic ones.

Thus, the correct answer is - sporophyte and gametophyte.
