(A) In a haplontic life cycle,the dominant,photosynthetic phase is the free-living gametophyte $(n)$.The zygote $(2n)$ is the only diploid stage,which undergoes meiosis to produce haploid spores $(n)$.These spores divide mitotically to form the gametophyte.This type of life cycle is characteristic of many algae,such as $Volvox$ and $Spirogyra$,and some species of $Chlamydomonas$.
