(N/A) $\rightarrow$ In a haplontic life cycle,the dominant,photosynthetic phase is the free-living gametophyte $(n)$.
$\rightarrow$ The gametophyte produces gametes through gametogenesis,which fuse during syngamy to form a diploid zygote $(2n)$.
$\rightarrow$ The zygote undergoes meiosis to form haploid spores $(n)$.
$\rightarrow$ These haploid spores divide mitotically to form the new gametophyte $(n)$.
$\rightarrow$ Many algae,such as $Volvox$,$Spirogyra$,and some species of $Chlamydomonas$,represent this pattern.
Chart Description:
- $A$: Represents the diploid $(2n)$ phase (Zygote).
- $B$: Represents the haploid $(n)$ phase (Gametophyte/Spores).
