What occurs in the life cycle of a moss but not in the life cycle of a gymnosperm?

The correct answer is:

In moss, sperm and egg cells are produced after haploid spores are separated from the sporophyte plant.

Explanation:

The life cycle of most mosses starts with the discharge of spores from a capsule, which begins when a small, lidlike structure, called the operculum, degenerates. A single spore develops to form a branched, filamentous protonema, from which a leafy gametophyte forms.
