Question

The gametophytes of an unknown plant are contained within the sporophyte, and the plant produces separate male and female gametophytes. Which the following is the best conclusion about the life cycle of this plant?
a. The plant is a fern, and the gametophyte is its dominant phase.
b. The plant is a gymnosperm, and the sporophyte is its dominant phase.
c. The plant is a moss, and the sporophyte is its dominant phase.
d. The plant is an angiosperm, and the gametophyte is its dominant phase.

Answer 1

Since the gametophyte is contained within the sporophyte, the sporophyte has to be the dominant phase. That leaves b and c, and mosses have separate, independent sporophyte and gametophyte phases.
