Question

Quizplus · Accepted Answer

Mosses have a dominant gametophyte generation where the plant appears as a small leafy or thalloid structure. This generation produces the sperm and eggs by mitosis. In ferns, gymnosperms, and angiosperms, the sporophyte generation is dominant and produces the gametophytes, which are much smaller and dependent on the sporophyte for nutrition.
