Which process must occur before the gametophyte generation?
Ber [7]
<span>The process must occur before the gametophyte generation is Sporophyte. A sporophyte is the diploid generation of a plant or alga that has a double set of chromosomes. [ All land plants, and some algae, have life cycles in which a multicellular haploid gametophyte generation alternates with a multicellular diploid generation.

In the flowering plants, the gametophytes are very reduced in size, and are represented by the pollen and the embryo sac.</span>
