THE WHY. “You may ask why plants even bother with such an odd and complicated life cycle. First, going through a haploid-only stage allows for the weeding out or removal of bad genes. Second, going through a diploid stage allows for genetic variation. Both of these help improve the overall survival of the plant species.” Thirdly, it allows the zygote to be dormant until favorable conditions occur.
