    Sporophytes
    a. develop from spores and produce gametes.
    B. are the dominant phase in the life cycle of most terrestrial plants.
    C. are the haploid stage of the plant life cycle.
    D. reproduce sexually.

    Answer: B. are the dominant phase in the life cycle of most terrestrial plants.

    Both Sporophyte and gametophyte stage can be dominant. Which generation is dominant differes in different plants. However in most terrestrial plants sporophytes are dominant.

    Sporophytes are the diploid stage. Gametophytes are the haploid stage.
    Sporophyte stage ...
